A watch having a double watch-surface and a method for disassembling the double watch-surface are provided. The watch includes a casing, in which an abutting ring portion is convexly provided; a first watch-surface which is placed on the top of the abutting ring portion; a second watch-surface which is placed at the bottom of the abutting ring portion; an snapping ring, the inner ring of which is annularly provided with a pressing portion and a groove; and a transparent cover engaged onto the groove. The two snapping rings are respectively engaged with the top surface and the bottom surface of the casing. The snapping ring is disposed on the abutting ring portion through the plural engaging protrusions. The pressing portion is pressed against the first and second watch-surfaces. Through the adjusting and snapping assembly, effect of engaging and fixing the two snapping rings to the casing can be achieved.

A device is provided for assembling a casing ring in a watch case middle including a bearing surface on an inner wall thereof, the casing ring including a housing opening in a lateral face of the casing ring, and in an upper or lower face of the casing ring. The device includes a locking part pivotable about a vertical axis of rotation passing through the upper or lower opening from a first position, in which the locking part is housed in the housing, to a second position, in which the locking part protrudes and abuts against the bearing surface of the inner wall of the case middle so as to hold the casing ring in the case middle. The locking part is snap-fitted in the housing and is pivotable about the vertical axis of rotation. A timepiece and a watch case fitted with the assembly device are also provided.

The disclosure provides an example watch. The watch includes (a) a housing having a first face and a second face and a cavity extending therebetween, where the first face includes a first bezel coupled to a first transparent watch crystal, (b) a disc disposed within the cavity between the first face and the second face and coupled to the housing, where the disc comprises a watch face for indicating time, and (c) a case cap removably coupled to the second face of the housing, where the case cap includes a casing having a first side configured to mate with the second face of the housing and a second side configured to be engraved.

The invention relates to watches. According to the invention, the watch comprises a case with a removable cover and a clock mechanism installed in the case, including a setting/winding mechanism. The watch is equipped with a combination lock used to block the setting/winding mechanism and block removing the cover from the case to prevent unauthorized use of the watch. The invention allows increasing the safety of using the watch due to the combination lock installed therein to block the setting/winding mechanism and block removing the cover from the case to prevent unauthorized use of the watch.

A watch case (10) including a back (30) driven into a middle (20) by a joint (40), and including a body (31) from which radially extends a lip (32), the body (31) including an axial annular shoulder (310) and the lip (32) including a radial annular shoulder (320). The middle (20) has an axial opening (21), an axial annular shoulder (200), and a radial annular shoulder (201) resting against the radial annular shoulder of the lip, the joint being interposed between the axial annular shoulders. The axial annular shoulders have peripheral profiles of complementary shapes, substantially circular, including one and the other, a first circular-arc-shaped portion having a first radius (R1, R2), and a second circular-arc-shaped portion to which is connected the first portion, having a second radius (r1, r2) the value of which is lower than that of the first radius (R1, R2).

A bezel (1) for a timepiece, including an annular slot (2) with a bottom (20) and two walls (21, 22), wherein a ring made of a luminescent material (3) is disposed on the bottom, the ring (3) being topped by a second ring (4) made of a mineral material occupying the volume of the slot. The bezel (1) includes in each of the two walls (21, 22) a seal (5, 5) cooperating with the second ring (4).

A timepiece case including a middle (20) receiving a horological movement (1) having at least one function corrector (10, 12) for carrying out various functions of activating, selecting, resetting and/or correcting a piece of information derived from the current time of the horological movement (1). The middle has a correction member (100), and a control stem (120) moving in translation within the cylindrical body of the correction member. The correction member (100) is mounted such that it slides in the middle (20) between a plurality of stable positions, each of the stable positions modifying the position of the end (122) of the control stem (120) facing the horological movement (1).

A notching system (100) including a spring (1) having a first toothset including n first teeth (11a, 12a) a first member (2) having a second toothset including m second teeth (22a, 22b), and a second member (3) mounted so as to be movable, in particular mounted so as to be rotatable, with respect to the first member (2), the first and second toothsets being arranged such that, through their interactions, they define p notches or indexed positions, the spring (1) including at least two elastic arms (11, 12), and at least one first pivot connection element (1b) between said two elastic arms (11, 12), the second member including at least one second pivot connection element (3b) cooperating with the at least one first pivot connection element (1b) in order to create at least one pivot connection between the spring (1) and the second member (3).
