Abstract: Case for a timepiece, including a middle part with an upper portion for receiving a movement surmounted by a dial carrying an upper sub-assembly or a crystal, and a lower portion cooperating with a back cover. This middle part includes a device for the removal or adjustment of this upper sub-assembly or crystal, which includes a plurality of pushers each movable in relation to this middle part in a sink of this middle part parallel to an axial direction, to transmit, directly or indirectly via a push plate, only to this dial, a force applied to each pusher in this direction from this lower portion and transmitted by this dial to this upper sub-assembly or crystal.

Abstract: Case (1) for a timepiece (1000), including a middle part (2) with an upper portion (21) for receiving a movement (100) surmounted by a dial (3) carrying an upper sub-assembly (4) or a crystal (40), and a lower portion (22) cooperating with a back cover (5). This middle part (2) includes a device (10) for the removal or adjustment of this upper sub-assembly (4) or crystal (40), which includes a plurality of pushers (6) each movable in relation to this middle part (2) in a sink (7) of this middle part (2) parallel to an axial direction (D), to transmit, directly or indirectly via a push plate (8), only to this dial (3), a force applied to each pusher (6) in this direction (D) from this lower portion (22) and transmitted by this dial (3) to this upper sub-assembly (4) or crystal (40).

Abstract: There is disclosed a method for manufacturing and mounting electric contacts for control members of small dimensions, particularly for control members used in the horological field.

Abstract: A timepiece including a case (24) provided with a back cover (28) and a middle part (26), a movement (30) mounted in the casing ring (32), a dial (34) mounted above the ring (32) and a crystal (36) mounted above the dial (34), said crystal (36) being provided with an annular collar (70) surrounding the flank (64) of the dial (34), characterised in that the casing ring (32) includes means (38) arranged to remove all the play inherent in the dimensional tolerances of the dial (34), the ring (32) and the back cover (28) of the case (24), these means (38) on which the collar (70) of the crystal (36) is supported being arranged at the upper end of the ring (32), along the outer circumference (86) thereof.

Abstract: The invention concerns a push button device for a timepiece, in particular a chronograph, including a pusher head (2) associated with a pusher stem (4) arranged so as to slide in a recess (6) inside which it moves axially from a rest position against the resilient return force of a spring (12) when the pusher head (2) is pushed in, characterised in that the pusher stem (4) is also able to move axially from its rest position to a pulled out position when the pusher head (2) is pulled out.

Abstract: A watch case (1) including a wall (6) with an outer face and an inner face, which defines a housing intended to accommodate a watch movement (7), and control means (4) able to have at least a first and a second state, which include a moving element (8) mounted so as to slide over the outer face of said wall (6) and able to occupy at least two positions, each position corresponding to one of said states. This watch case is characterised in that said control means (4) further include a push button (9), mounted so as to slide in a hole (6a) passing through said wall (6) and provided with an inner end (9a) intended to co-operate with said movement (7) and with an outer end (9b) co-operating with said moving element (8) and a body in contact with a sealing gasket (10) inserted between said push button (9) and said wall (6).
