Abstract: A timepiece (1) including a case (4) in which a horology movement (2) is turned. The movement (2) is held in the case (4) by a shock-absorbing fastening (10), the shock-absorbing fastening (10) including at least two blades (3), each blade (3) having two opposite ends (3c, 3d) attached, directly or indirectly, to the case (4) and to the horology movement (2) by fastening elements (7) engaging with first anchor points on the horology movement (2) and with second anchor points on the case (4). The first anchor points on the horology movement are inscribed on a first circle (C1) and the second anchor points are inscribed on a second circle (C2), the first circle (C1) and the second circle (C2) being concentric. The first anchor points (8a) and the second anchor points (8b) are not radially aligned.

Abstract: A device (10) for fastening a horology movement (2) designed to hold the horology movement (2) in a case (4) of a timepiece (1). The device includes at least one stack (3) with at least two blades (3a, 3b), the at least one stack (3) having two opposite ends, a first case end (3c) and a second movement end (3d). The device also includes first fastening elements (7) for fastening the second movement end (3d) of the at least one stack (3) to the horology movement (2), the at least one stack (3) being configured to rigidly hold the horology movement (2) in the case (4).

Abstract: A timepiece (100) including a middle (10), a detachable back (12) mounted on the middle (10), a movement (20) and casing elements (30) for rigidly holding the movement (20) in an inner volume (15) of the middle (10), having a first casing circle (35) pressing against a shoulder (16) formed in the middle (10); a second casing circle (34), the movement (20) being rigidly held between the first casing circle (35) and the second casing element (34) via a peripheral rib (21) of the horology movement (20), the first casing circle (35) and the second casing circle (34) being superimposed with no direct contact with each other; a clamping element (33), separate from the detachable back (12), in direct contact with the second casing circle (34).

Abstract: A watch (100) including a middle (10), a detachable back (12) mounted on the middle (10), and a movement (20) housed in an inner volume (15) of the middle (10). The watch also includes a dial (40), with a thickness (e3), having an upper face (41) visible to the user, the dial (40) being attached to a reinforcement piece (30) positioned under the dial (40), the reinforcement piece (30) including a peripheral annular shoulder (36) engaging with an annular shoulder (16) formed in the middle (10), the reinforcement piece (30) being attached to the middle (10) pressing against the annular shoulder (16) of the middle (10).

Abstract: A water-resistant closing device for a watch case, the device including an annular gasket (1) arranged to be placed between a middle (2) and a back (3), a bezel or a crystal (4), or a bezel and a crystal, or a back and a crystal. The gasket (1) has on its middle portion a bulge (10) protruding on its outer lateral face (11), the bulge being arranged to be engaged against the middle (3) and compressed following the installation of the back or of the crystal on the middle, the bulge being delimited by an upper (12) and lower material countersink (13) on either side of the bulge (10) in the non-compressed state of the gasket (1) to facilitate its installation and its deformation.

Abstract: Provided is a device for fastening a back on a middle portion of a watch. The back includes a cover arranged to form a bearing surface with the middle portion and a body arranged to rest in the middle portion. The device includes an indexing ring disposed between the back and the middle portion, and the ring includes at least one lower catch arranged to cooperate with the back and ensure the indexing with the back and an upper catch are arranged to cooperate with the middle portion and ensure the indexing of the back and ring assembly in relation to the middle portion, and the upper catch has a height greater than that of the lower catch, or vice versa.

Abstract: 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).

Abstract: A device is for fastening a back on a middle of a watch. The back includes a cover arranged to form a bearing surface with the middle and a body arranged to rest in the middle. The device includes a ring disposed between the back and the middle, the ring being arranged to ensure the water resistance and indexing of the back. The ring includes an upper part ensuring the water resistance and a median part including positioning to ensure precise placement of the back.
