Abstract

The timepiece comprises a frame ( 3 ) in which a watch case ( 7, 8, 9 ) is reversibly mounted. The watch case ( 7, 8, 9 ) is rotatable within the frame ( 3 ) around a determined axis ( 22 ) traversing the flank ( 24 ) of the watch case ( 7, 8, 9 ) and the inner flank ( 25 ) of the frame ( 3 ). The flank ( 24 ) of the watch case ( 7, 8, 9 ) and the inner flank ( 25 ) of the frame ( 3 ) substantially are parts of a same surface of rotation around the determined axis ( 22 ) so as to reduce the gap between the frame ( 3 ) and the watch case ( 7, 8, 9 ).

En référence aux figures 1 à 10, une pièce d'horlogerie du type montre-bracelet selon un premier mode de réalisation de l'invention comprend un berceau 1 de forme générale circulaire muni, à deux extrémités diamétralement opposées, d'éléments 2a, 2b d'attache à un bracelet (non représenté). Un cadre-châssis sans fond 3, de forme annulaire et ayant un diamètre externe plus grand que le diamètre du berceau 1, est articulé par une de ses extrémités à une extrémité du berceau 1 au moyen d'une charnière 4 et, en position de repos, est superposé au berceau 1 de façon concentrique avec ce dernier (figure 2). Ce cadre-châssis 3 est constitué de deux pièces, un cadre inférieur 3a et un cadre supérieur 3b, assemblées l'une à l'autre au moyen de vis 3c (figure 7) régulièrement réparties dans le cadre-châssis 3 et vissées chacune dans un trou borgne taraudé correspondant 3d formé dans le cadre-châssis 3. Les vis 3c, dont une seule est visible à la figure 7, sont typiquement au nombre de quatre mais peuvent bien entendu être en nombre différent si cela est souhaité. Afin que ces vis 3c ne soient pas visibles lorsque la montre est au poignet de l'utilisateur et le cadre-châssis 3 en position de repos, les trous borgnes 3d débouchent sur la surface inférieure, désignée par 3e, du cadre-châssis 3.With reference to Figures 1 to 10 , a timepiece of the wristwatch type according to a first embodiment of the invention comprises a cradle 1 of generally circular shape provided, at two diametrically opposite ends, with elements 2a, 2b for attaching to a bracelet ( not shown). A bottomless frame 3, annular in shape and having an external diameter greater than the diameter of the cradle 1, is articulated by one of its ends to one end of the cradle 1 by means of a hinge 4 and, in the position of rest, is superimposed on the cradle 1 concentrically with the latter ( figure 2 ). This frame-frame 3 consists of two parts, a lower frame 3a and an upper frame 3b, assembled to one another by means of screws 3c ( figure 7 ) regularly distributed in the frame-frame 3 and each screwed into a corresponding threaded blind hole 3d formed in the frame-frame 3. The screws 3c, only one of which is visible at the figure 7 are typically four in number but may of course be different in number if desired. So that these screws 3c are not visible when the watch is on the wrist of the user and the frame-frame 3 in the rest position, the blind holes 3d open on the lower surface, designated by 3e, of the frame-frame 3.

Comme cela apparaît sur les figures 1 à 4, la charnière 4 est constituée d'une partie centrale 4a, d'une partie extérieure 4b faisant partie du cadre-châssis 3 et plus particulièrement de la pièce inférieure 3a de ce cadre-châssis 3, et de vis 4c logées à l'intérieur de ces parties centrale et extérieure 4a, 4b et définissant l'axe de la charnière.As it appears on the Figures 1 to 4 , the hinge 4 consists of a central portion 4a, an outer portion 4b forming part of the frame-frame 3 and more particularly the lower part 3a of the frame-frame 3, and 4c screws housed inside of these central and outer parts 4a, 4b and defining the axis of the hinge.

Deux évidements complémentaires formés respectivement dans les pièces 3a, 3b du cadre-châssis 3 et situés au droit de la charnière 4 définissent un trou borgne 3f (figure 6) débouchant dans l'intérieur du cadre-châssis 3 (figure 6). Ce trou borgne 3f reçoit une première extrémité 5a d'une cheville 5. Deux autres évidements complémentaires formés respectivement dans les pièces 3a, 3b, à l'opposé diamétralement du trou borgne 3f, définissent un trou traversant 3g permettant le passage à travers la paroi du cadre-châssis 3 d'un tube de couronne 6. La cheville 5 et le tube de couronne 6 sont solidaires d'une boîte de montre comprenant une lunette ou carrure 7, un fond 8 et un cercle 9 et servent de support à cette boîte de montre dans le cadre-châssis 3. Plus particulièrement, une seconde extrémité 5b de la cheville 5 est vissée et collée dans le cercle 9 et une première extrémité 6a du tube de couronne 6 est chassée et collée dans ce même cercle 9. La seconde extrémité 6b du tube de couronne 6 est, elle, connectée à une couronne de mise à l'heure 10 à l'extérieur du cadre-châssis 3. Le cercle 9 est constitué d'une seule pièce et est disposé dans un logement formé en partie dans la lunette 7 et en partie dans le fond 8, c'est-à-dire un logement défini par deux évidements complémentaires formés sur les faces internes respectives de la lunette 7 et du fond 8. Le cercle 9 loge lui-même un mouvement d'horlogerie 11 et un cadran 12, ce dernier étant surmonté d'une glace 13 montée dans la lunette 7. Des trous traversants diamétralement opposés 14, 15 formés chacun en partie dans la lunette 7 et en partie dans le fond 8 entre le logement du cercle 9 et la face interne du cadre-châssis 3 permettent le passage, respectivement, de la cheville 5 et du tube de couronne 6.Two complementary recesses formed respectively in the parts 3a, 3b of the frame-frame 3 and located at the right of the hinge 4 define a blind hole 3f ( figure 6 ) opening into the interior of the frame-frame 3 ( figure 6 ). This blind hole 3f receives a first end 5a of an ankle 5. Two other complementary recesses formed respectively in the pieces 3a, 3b, to diametrically opposite the blind hole 3f, define a through hole 3g allowing the passage through the wall of the frame-frame 3 of a crown tube 6. The pin 5 and the crown tube 6 are integral with a box of watch comprising a bezel or middle 7, a bottom 8 and a circle 9 and serve as a support for this watch case in the frame-frame 3. More particularly, a second end 5b of the pin 5 is screwed and glued in the circle 9 and a first end 6a of the crown tube 6 is driven and glued in the same circle 9. The second end 6b of the crown tube 6 is connected to a setting ring 10 on the outside of the frame -chassis 3. The circle 9 consists of a single piece and is arranged in a housing formed partly in the bezel 7 and partly in the bottom 8, that is to say a housing defined by two complementary recesses formed on the respective internal faces of the The circle 9 itself houses a clockwork movement 11 and a dial 12, the latter being surmounted by an ice-cream 13 mounted in the telescope 7. By diametrically opposite through-holes 14, 15 each formed partially in the bezel 7 and partly in the bottom 8 between the housing of the circle 9 and the inner face of the frame-frame 3 allow the passage, respectively, of the pin 5 and the crown tube 6.

Avantageusement, la lunette 7 et le fond 8 sont fixés l'un à l'autre par des cloches d'assemblage 16, typiquement au nombre de quatre, régulièrement réparties le long de la périphérie de l'ensemble lunette 7-fond 8 (l'une de ces cloches 16 est représentée à la figure 8). Chaque cloche d'assemblage 16 a une forme générale cylindrique et comporte sur l'une de ses faces un évidement tronconique central 16a. Chaque cloche d'assemblage 16 est logée entièrement dans un logement de forme correspondante ménagé en partie dans la lunette 7 et en partie dans le fond 8 et est maintenue fermement dans ce logement par une vis 17 s'étendant dans le plan de la cheville 5 et du tube de couronne 6 successivement à travers un trou traversant central 18 formé dans la cloche 16 et un trou traversant 19 formé en partie dans la lunette 7 et en partie dans le fond 8 et jusqu'à l'intérieur d'un trou borgne taraudé 20 formé dans le cercle 9. Le trou borgne taraudé 20 reçoit l'extrémité filetée de la vis 17. La tête de la vis 17, quant à elle, est logée entièrement dans le trou traversant central 18 de la cloche 16 et s'appuie contre un épaulement 21 défini par ce trou 18. Chaque cloche d'assemblage 16 constitue ainsi un élément ancré à la fois dans la lunette 7 et le fond 8. En position d'utilisation de la montre, les cloches d'assemblage 16 sont en regard de la face interne du cadre-châssis 3 et sont donc cachées par ce dernier, comme représenté sur la figure 8.Advantageously, the bezel 7 and the bottom 8 are fixed to each other by assembly bells 16, typically four in number, evenly distributed along the periphery of the bezel assembly 7-bottom 8 (FIG. one of these bells 16 is shown in FIG. figure 8 ). Each assembly bell 16 has a generally cylindrical shape and has on one of its faces a central frustoconical recess 16a. Each assembly bell 16 is housed entirely in a recess of corresponding shape formed partly in the telescope 7 and partly in the bottom 8 and is held firmly in this housing by a screw 17 extending in the plane of the ankle 5 and the crown tube 6 successively through a central through hole 18 formed in the bell 16 and a through hole 19 formed partly in the telescope 7 and partly in the bottom 8 and to the inside of a threaded blind hole 20 formed in the circle 9. The threaded blind hole 20 receives the threaded end of the screw 17. The screw head 17, for its part, is housed entirely in the central through hole 18 of the bell 16 and bears against a shoulder 21 defined by this hole 18. Each assembly bell 16 thus constitutes an element anchored both in the telescope 7 and the bottom 8. In the position of use of the watch, the assembly bells 16 are opposite the inner face of the frame-frame 3 and are thus hidden by the latter, as shown in FIG. figure 8 .

En référence de nouveau à la figure 6, la cheville 5 est constituée d'un corps cylindrique 5c terminé au niveau de l'extrémité 5a par une portion hémisphérique et au niveau de l'extrémité 5b par une saillie. La saillie 5b et une partie du corps cylindrique 5c sont logées dans le cercle 9 tandis que la portion hémisphérique 5a et une partie du corps cylindrique 5c sont logées librement, c'est-à-dire sans y être fixées, dans le trou borgne 3f. Le fond du trou borgne 3f a une forme hémisphérique correspondant à celle de l'extrémité 5a de la cheville 5. Cette forme hémisphérique facilite la réalisation du trou borgne 3f en permettant le fraisage de chacun des deux demi-trous composant le trou 3f par une fraise sphérique placée perpendiculairement au plan du cadre correspondant 3a, 3b du cadre-châssis 3. La cheville 5 et le tube de couronne 6 définissent ensemble un axe de rotation géométrique diamétral 22 de la boîte de montre 7, 8, 9 par rapport au cadre-châssis 3.Referring back to the figure 6 , the peg 5 consists of a cylindrical body 5c terminated at the end 5a by a hemispherical portion and at the end 5b by a projection. The projection 5b and a portion of the cylindrical body 5c are housed in the circle 9 while the hemispherical portion 5a and a portion of the cylindrical body 5c are housed freely, that is to say without being fixed, in the blind hole 3f . The bottom of the blind hole 3f has a hemispherical shape corresponding to that of the end 5a of the pin 5. This hemispherical shape facilitates the realization of the blind hole 3f by allowing the milling of each of the two half-holes forming the hole 3f by a spherical cutter placed perpendicular to the plane of the corresponding frame 3a, 3b of the frame-frame 3. The peg 5 and the crown tube 6 together define a diametrical geometric rotation axis 22 of the watch case 7, 8, 9 with respect to the frame - chassis 3.

Par ce montage de la boîte de montre 7, 8, 9 dans le cadre-châssis 3, la boîte de montre 7, 8, 9 est réversible et peut ainsi prendre deux positions de repos, ou positions d'utilisation, parallèles au cadre-châssis 3. Dans la première position, illustrée à la figure 6, le cadran 12 est visible et le fond 8 est caché. Dans la seconde position (non représentée), le cadran 12 est en regard de la face supérieure du berceau 1 et est donc caché, et la face externe du fond 8 est visible. Cette face externe du fond 8 peut à cet effet comporter un décor, tel que des émaux, transformant la montre en une pièce de bijouterie. En variante toutefois, le fond 8 pourrait être remplacé par une seconde lunette portant un second cadran et produisant un effet esthétique différent de celui de la lunette 7 associée au cadran 12.By this mounting of the watch case 7, 8, 9 in the frame-frame 3, the watch case 7, 8, 9 is reversible and can thus take two rest positions, or positions of use, parallel to the frame. 3. In the first position, illustrated in figure 6 , the dial 12 is visible and the bottom 8 is hidden. In the second position (not shown), the dial 12 is opposite the upper face of the cradle 1 and is therefore hidden, and the outer face of the bottom 8 is visible. This outer face of the bottom 8 may for this purpose include a decor, such as enamels, transforming the watch into a piece of jewelry. Alternatively, however, the bottom 8 could be replaced by a second bezel carrying a second dial and producing an aesthetic effect different from that of the bezel 7 associated with the dial 12.

Pour retourner la boîte de montre 7, 8, 9 dans le cadre-châssis 3, c'est-à-dire la faire passer d'une position de repos à l'autre, on fait d'abord pivoter par rapport au berceau 1, autour de l'axe de rotation défini par la charnière 4, l'ensemble constitué par le cadre-châssis 3 et la boîte de montre 7, 8, 9, comme montré à la figure 1, jusqu'à ce que cet ensemble 3, 7, 8, 9 fasse un angle suffisant avec le berceau 1. Puis, comme montré à la figure 10, on fait pivoter la boîte de montre 7, 8, 9 dans le cadre-châssis 3 de 180° sur elle-même, autour de l'axe de rotation 22 fixe par rapport au cadre-châssis 3, pour que le fond 8 prenne la place de la lunette 7 et réciproquement. On rabat ensuite l'ensemble constitué par le cadre-châssis 3 et la boîte de montre 7, 8, 9 sur le berceau 1. On notera que, du fait que les éléments 2a, 2b d'attache au bracelet sont solidaires du berceau 1 et indépendants du cadre-châssis 3, la boîte de montre 7, 8, 9 peut être retournée alors que la montre est au poignet de l'utilisateur.To turn the watch case 7, 8, 9 in the frame-frame 3, that is to say to move it from one rest position to another, it is first rotated relative to the cradle 1 around the axis of rotation defined by the hinge 4, the assembly constituted by the frame-frame 3 and the watch case 7, 8, 9, as shown in FIG. figure 1 , until this assembly 3, 7, 8, 9 makes a sufficient angle with the cradle 1. Then, as shown in FIG. figure 10 , the watch case 7, 8, 9 is pivoted in the frame-chassis 3 by 180 ° on itself, around the axis of rotation 22 fixed relative to the frame-frame 3, so that the bottom 8 takes the place of the telescope 7 and vice versa. The assembly constituted by the frame-frame 3 and the watch case 7, 8, 9 is then folded onto the cradle 1. It will be noted that, since the elements 2 a, 2 b attaching to the bracelet are integral with the cradle 1 and independent of the frame-frame 3, the watch case 7, 8, 9 can be returned while the watch is on the wrist of the user.

En référence de nouveau à la figure 6, deux bagues métalliques 23a, 23b sont logées dans des cavités respectives diamétralement opposées pratiquées dans le flanc ou pourtour 24 de la boîte de montre 7, 8, 9 autour respectivement de la cheville 5 et du tube de couronne 6 et dépassent très légèrement de ce flanc 24 à l'extérieur de la boîte de montre 7, 8, 9. Ces bagues 23a, 23b sont en contact frictionnel avec le flanc ou face interne, désigné par 25, du cadre-châssis 3 et servent à supprimer le jeu dans la direction de l'axe 22 entre les flancs respectifs 24, 25 de la boîte de montre 7, 8, 9 et du cadre-châssis 3 et à empêcher que ces flancs 24, 25 ne se touchent. Des joints annulaires de friction 28a, 28b sont entourés et maintenus en compression dans le flanc 24 contre respectivement la périphérie de la cheville 5 et celle du tube de couronne 6 par les bagues 23a, 23b. Ces joints 28a, 28b ont pour fonction d'exercer une friction contre le flanc interne 25 du cadre-châssis 3 lors de la rotation de la boîte de montre 7, 8, 9 pour faire en sorte que la boîte de montre 7, 8, 9 ne tourne pas intempestivement dans le cadre-châssis 3 mais seulement sous l'effet d'un couple imprimé par l'utilisateur. Dans une variante de réalisation de l'invention, ces bagues 23a, 23b et ces joints 28a, 28b pourraient être logés dans le flanc interne 25 du cadre-châssis 3 et exercer une friction contre le flanc 24 de la boîte de montre 7, 8, 9.Referring back to the figure 6 two metal rings 23a, 23b are housed in respective diametrically opposite cavities formed in the flank or periphery 24 of the watch case 7, 8, 9 respectively around the ankle 5 and the crown tube 6 and slightly exceed this flank 24 outside of the watch case 7, 8, 9. These rings 23a, 23b are in frictional contact with the sidewall or internal face, indicated by 25, of the frame-frame 3 and are used to eliminate the clearance in the direction of the axis 22 between the respective flanks 24, 25 of the watch case 7, 8, 9 and the frame-frame 3 and to prevent these flanks 24, 25 from touching each other. Annular friction joints 28a, 28b are surrounded and held in compression in the sidewall 24 respectively against the periphery of the pin 5 and that of the crown tube 6 by the rings 23a, 23b. These seals 28a, 28b have the function of exerting friction against the inner side 25 of the frame-frame 3 during the rotation of the watch case 7, 8, 9 to make so that the watch case 7, 8, 9 does not turn unexpectedly in the frame-frame 3 but only under the effect of a torque printed by the user. In an alternative embodiment of the invention, these rings 23a, 23b and these seals 28a, 28b could be housed in the inner side 25 of the frame-frame 3 and exert friction against the side 24 of the watch case 7, 8 , 9.

De préférence, des moyens de verrouillage sont en outre prévus pour maintenir de façon déverrouillable le cadre-châssis 3 dans sa position de repos par rapport au berceau 1 (figures 2, 3). Ces moyens de verrouillage sont avantageusement sous la forme de deux butées à bille 26a, 26b logées dans deux saillies respectives 1 a, 1 b du berceau 1 situées de part et d'autre de la couronne 10 et faisant office de protège-couronne, les billes 26c, 26d de ces butées s'encliquetant dans des évidements correspondants 27 formés dans le flanc externe du cadre-châssis 3 (figures 3, 5, 9). D'autres moyens de verrouillage (non représentés) peuvent également être prévus pour maintenir de façon déverrouillable la boîte de montre 7, 8, 9 dans l'une ou l'autre de ses positions de repos par rapport au cadre-châssis 3.Preferably, locking means are furthermore provided for releasably holding the chassis frame 3 in its rest position with respect to the cradle 1 ( figures 2 , 3 ). These locking means are advantageously in the form of two ball stops 26a, 26b housed in two respective projections 1a, 1b of the cradle 1 located on either side of the ring 10 and acting as a crown guard, the balls 26c, 26d of these abutments snapping into corresponding recesses 27 formed in the outer side of the frame-frame 3 ( figures 3 , 5 , 9 ). Other locking means (not shown) may also be provided for releasably holding the watch case 7, 8, 9 in one or the other of its rest positions relative to the frame-frame 3.

La montre selon l'invention est par ailleurs rendue étanche par des joints annulaires 29a, 29b maintenus en compression entre la lunette 7, respectivement le fond 8, et le cercle 9, et un joint annulaire 30 maintenu en compression entre la lunette 7 et la glace 13. D'autre part, le collage de l'extrémité 5b de la cheville 5 et de l'extrémité 6a du tube de couronne 6 dans le cercle 9 est effectué au moyen d'une colle d'étanchéité.The watch according to the invention is also sealed by annular seals 29a, 29b held in compression between the bezel 7, respectively the bottom 8, and the circle 9, and an annular seal 30 held in compression between the bezel 7 and the ice 13. On the other hand, the bonding of the end 5b of the pin 5 and the end 6a of the crown tube 6 in the circle 9 is effected by means of a sealing glue.

Conformément à l'invention, afin de supprimer ou au moins réduire le jour apparaissant entre la boîte de montre 7, 8, 9 et le cadre-châssis 3, le flanc 24 de la boîte de montre 7, 8, 9 et le flanc interne 25 du cadre-châssis 3 sont sensiblement des portions d'une même surface de révolution 31 autour de l'axe de rotation 22. De cette façon, lors des mouvements de rotation sur elle-même de la boîte de montre 7, 8, 9 dans le cadre-châssis 3, le flanc 24 de la boîte de montre 7, 8, 9 épouse le flanc interne 25 du cadre-châssis 3.According to the invention, in order to eliminate or at least reduce the day appearing between the watch case 7, 8, 9 and the frame-frame 3, the side 24 of the watch case 7, 8, 9 and the internal sidewall 25 of the frame-chassis 3 are substantially portions of the same surface of revolution 31 around the axis of rotation 22. In this way, during the rotational movements on itself of the watch case 7, 8, 9 in the frame-frame 3, the side 24 of the watch case 7, 8, 9 matches the inner side 25 of the frame-frame 3.

Dans l'exemple illustré aux figures 1 à 10, la surface de révolution 31 est une sphère dont le centre O est situé sur l'axe 22, et les flancs 24, 25 sont des portions de cette sphère délimitées chacune par deux plans parallèles situés de part et d'autre de l'axe 22 et symétriques par rapport à cet axe 22 (cf. figure 6). Les figures 11 et 12 illustrent deux autres modes de réalisation, dans lesquels le flanc de la boîte de montre et le flanc interne du cadre-châssis présentent chacun des discontinuités de forme. Sur les figures 11 et 12, pour des raisons de clarté, seule la boîte de montre a été représentée, mais on comprendra que le flanc interne du cadre-châssis a la même forme que le flanc de la boîte de montre. Comme cela apparaît sur ces figures 11 et 12, le flanc de la boîte de montre est constitué de deux premières portions opposées situées de part et d'autre de l'axe de rotation 22 et de deux secondes portions opposées coupant l'axe de rotation 22 et raccordant les premières portions entre elles. Dans le mode de réalisation illustré à la figure 11, les premières portions, désignées par 32a, 32b, ont, dans un plan perpendiculaire à l'axe de rotation 22, un premier rayon de courbure R1 et un centre de courbure C1 situé sur l'axe 22 (cf. figure 11 b) et, dans un plan contenant l'axe 22 et perpendiculaire au plan précité, un second rayon de courbure R2 supérieur au rayon R1 (cf. figure 11 c) ; les secondes portions, désignées par 33a, 33b, ont, elles, une forme sphérique de rayon de courbure R3 (cf. figures 11c et 11d) et leurs centres de courbure respectifs sont situés sur l'axe 22. Dans le mode de réalisation illustré à la figure 12, les premières portions, désignées par 34a, 34b, ont, dans un plan perpendiculaire à l'axe de rotation 22, un rayon de courbure R4 et un centre de courbure C4 situé sur l'axe 22 (cf. figure 12b) et sont droites dans un plan contenant l'axe 22 et perpendiculaire au plan précité (cf. figure 12c) ; les secondes portions, désignées par 35a, 35b, sont, elles, planes et perpendiculaires à l'axe 22. Le flanc 34a, 35a, 34b, 35b consiste ainsi en une portion d'un cylindre délimitée par deux plans parallèles entre eux, situés de part et d'autre de l'axe 22 et parallèles à ce dernier.In the example shown in Figures 1 to 10 , the surface of revolution 31 is a sphere whose center O is located on the axis 22, and the flanks 24, 25 are portions of this sphere delimited each by two parallel planes located on either side of the axis 22 and symmetrical with respect to this axis 22 (cf. figure 6 ). The figures 11 and 12 illustrate two other embodiments, wherein the sidewall of the watch case and the inner side of the frame-frame each have discontinuities form. On the figures 11 and 12 for the sake of clarity, only the watch case has been shown, but it will be understood that the inner side of the frame-frame has the same shape as the side of the watch case. As it appears on these figures 11 and 12 , the side of the watch case consists of two first opposite portions located on either side of the axis of rotation 22 and two second opposite portions intersecting the axis of rotation 22 and connecting the first portions between them. In the embodiment illustrated in figure 11 , the first portions, designated 32a, 32b, have, in a plane perpendicular to the axis of rotation 22, a first radius of curvature R1 and a center of curvature C1 located on the axis 22 (cf. figure 11 (b) and, in a plane containing the axis 22 and perpendicular to the aforementioned plane, a second radius of curvature R2 greater than the radius R1 (cf. Figure 11 (c) ; the second portions, designated 33a, 33b, have a spherical shape of radius of curvature R3 (cf. Figures 11c and 11d ) and their respective centers of curvature are located on the axis 22. In the embodiment illustrated in FIG. figure 12 , the first portions, designated 34a, 34b, have, in a plane perpendicular to the axis of rotation 22, a radius of curvature R4 and a center of curvature C4 located on the axis 22 (cf. figure 12b ) and are straight in a plane containing the axis 22 and perpendicular to the aforementioned plane (cf. figure 12c ); the second portions, designated 35a, 35b, are flat and perpendicular to the axis 22. The flank 34a, 35a, 34b, 35b thus consists of a portion of a cylinder delimited by two parallel planes between them, located on both sides of the axis 22 and parallel to the latter.

Dans chacun des modes de réalisation illustrés aux figures 1-10, 11 et 12, l'axe de rotation 22 est un axe de symétrie pour le flanc de la boîte de montre et le flanc interne du cadre-châssis et ces flancs ont une même hauteur H constante (cf. figure 6). En variante, toutefois, l'axe de rotation 22, tout en étant situé dans un plan de symétrie du flanc de la boîte de montre perpendiculaire au plan de la boîte de montre pourrait être excentré par rapport à ce flanc, c'est-à-dire que le flanc de la boîte de montre pourrait avoir une hauteur plus grande d'un côté de l'axe 22 que de l'autre, par exemple pour conférer un aspect esthétique particulier à la montre dans l'une des deux positions de repos de la boîte de montre à l'intérieur du cadre-châssis. En variante également, le flanc de la boîte de montre et le flanc interne du cadre-châssis pourraient avoir une hauteur différente, par exemple le flanc de la boîte de montre pourrait avoir une plus grande hauteur que le flanc interne du cadre-châssis pour conférer un effet esthétique particulier.In each of the embodiments illustrated in Figures 1-10 , 11 and 12 , the axis of rotation 22 is an axis of symmetry for the side of the watch case and the inner side of the frame-frame and these sides have the same constant height H (cf. figure 6 ). Alternatively, however, the axis of rotation 22, while being located in a plane of symmetry of the side of the watch case perpendicular to the plane of the watch case could be eccentric with respect to this flank, that is to say that is, that the side of the watch case could have a greater height on one side of the axis 22 than on the other, for example to give a particular aesthetic appearance to the watch in one of the two positions of rest of the watch case inside the frame-frame. Alternatively also the sidewall of the watch case and the inner side of the frame-frame could have a different height, for example the side of the watch case could have a greater height than the inner side of the frame-frame to confer a particular aesthetic effect.

Par ailleurs, bien que le cadre-châssis tel que représenté aux figures 1 à 10 soit fermé, c'est-à-dire entoure la boîte de montre sur tout le pourtour de celle-ci, le cadre-châssis de la montre selon l'invention pourrait en variante être ouvert. En particulier, dans le cas des exemples illustrés aux figures 11 et 12, le cadre-châssis pourrait être en forme de U.Moreover, although the chassis frame as shown in Figures 1 to 10 is closed, that is to say, surrounds the watch case around the entire periphery thereof, the frame-frame of the watch according to the invention could alternatively be open. In particular, in the case of the examples illustrated in figures 11 and 12 , the frame-chassis could be U-shaped.

En référence de nouveau aux figures 1 à 10, le montage de la montre selon l'invention est effectué de la manière suivante :

  1. 1. Le tube de couronne 6 est chassé et collé de façon étanche dans le cercle 9 et la cheville 5 est vissée et collée de façon étanche dans ce même cercle 9.
  2. 2. Le mouvement d'horlogerie 11 et le cadran 12 avec les aiguilles correspondantes sont montés dans le cercle 9.
  3. 3. La glace 13 et sa manchette (joint d'étanchéité annulaire 30) sont chassées dans la lunette 7.
  4. 4. Le joint d'étanchéité 29a est monté dans la lunette 7. L'ensemble constitué par le cercle 9, le mouvement 11 et le cadran 12 est placé dans la lunette 7. Le joint d'étanchéité 29b est posé contre le cercle 9 et le fond 8 est positionné. Tout en maintenant cet ensemble 7-9, 11, 12 entre deux doigts, les cloches d'assemblage 16 sont placées dans leurs logements respectifs puis vissées dans le cercle 9.
  5. 5. L'ensemble 7-9, 11, 12 est placé dans les cadres inférieur 3a et supérieur 3b formant le cadre-châssis 3 puis les cadres 3a, 3b sont fixés l'un à l'autre par les vis 3c. On notera à cet égard qu'une fonction des deux cadres 3a, 3b est de rendre possible le montage dans le cadre-châssis 3 de l'ensemble 7-9,11,12 compte tenu de la quasi-absence de jeu entre la boîte de montre 7-9 et le cadre-châssis 3 et de la forme en portion de surface de révolution du flanc 24 de la boîte de montre 7-9 et du flanc interne 25 du cadre-châssis 3.
  6. 6. Les butées à bille 26a, 26b sont chassées dans les saillies 1 a, 1 b du berceau 1 et les vis 4c sont placées dans les parties de charnière 4a, 4b pour articuler l'ensemble 3, 7-9, 11, 12 au berceau 1.
With reference again to Figures 1 to 10 , the assembly of the watch according to the invention is carried out as follows:
  1. 1. The crown tube 6 is driven and sealed in the circle 9 and the pin 5 is screwed and sealed in the same circle 9.
  2. 2. The watch movement 11 and the dial 12 with the corresponding hands are mounted in the circle 9.
  3. 3. The ice 13 and its sleeve (annular seal 30) are driven into the bezel 7.
  4. 4. The seal 29a is mounted in the bezel 7. The assembly consisting of the circle 9, the movement 11 and the dial 12 is placed in the bezel 7. The seal 29b is placed against the circle 9 and the bottom 8 is positioned. While maintaining this assembly 7-9, 11, 12 between two fingers, the assembly bells 16 are placed in their respective housings and then screwed into the circle 9.
  5. 5. The assembly 7-9, 11, 12 is placed in the lower frames 3a and upper 3b forming the frame-frame 3 and the frames 3a, 3b are fixed to each other by the screws 3c. Note in this regard that a function of the two frames 3a, 3b is to make possible the mounting in the frame-frame 3 of the assembly 7-9,11,12 given the virtual absence of play between the box 7-9 and the frame-frame 3 and the portion of the surface of revolution of the side 24 of the watch case 7-9 and the inner side 25 of the frame-frame 3.
  6. 6. The thrust bearings 26a, 26b are driven into the projections 1a, 1b of the cradle 1 and the screws 4c are placed in the hinge parts 4a, 4b to articulate the assembly 3, 7-9, 11, 12 in the cradle 1.
