Said downstream stage (1) includes a second hour ratchet (15) which pivots about said axis (D) and whose toothing is inclined in the same direction as that of said first hour ratchet (13).

Abstract: Safety mechanism against inadvertent actuation for a timepiece (1000) with a motion work driving a release cam (530), which pivots a release lever (105) towards a ratchet (9) of a striking mechanism unit (2) of a striking mechanism (100) including a minute repeater actuated by pressing on a first lever (535), wherein, when a strike is operated, said unit (2) drives a plate (525) carrying a winding cam (440).

Abstract: The striking mechanism for a watch includes a gong, which is connected to a gong-carrier, a hammer for striking the gong at pre-determined times, a damper counterspring for keeping the hammer at a distance from the gong in an idle mode, and a hammer drive spring, which includes a fixed end and an end that is free to move. The striking mechanism includes a locking device, which is provided with at least one rotating bolt. This bolt includes a first arm provided with a hook for hooking onto a notch of the hammer to lock the hammer in an idle mode. The locking device is arranged to lock the hammer following a single strike of the hammer against the gong in a strike mode.

At least one insulator part (6) of the insulator arrangement is configured to be moved in rotation by drive means (9, 11, 12) so that one U-shaped portion (16) of the insulator part comes into contact with the gong in an idle mode or is at a distance from the gong in striking mode. A rotatably mounted, opposite insulator counterpart (7) with a rod (17) is provided so that the insulator part (6) and the opposite counterpart form a clamp for imprisoning the gong in an idle mode.

The alarm watch also includes an alarm mechanism able to release an alarm at a predetermined alarm time, manually determined every twenty-four hours, and a mechanism for displaying the predetermined alarm time. The alarm time display mechanism includes at least a second hour hand (33) provided for displaying the alarm time in twelve hours, and an indicator (52) with two positions provided for specifying whether the alarm time is situated between midnight and midday (AM) or situated between midday and midnight (PM).

Abstract: The invention concerns a timepiece gear train including at least one pair of circular toothed elements (25, 31) with parallel axes, the elements being provided with respectively toothings that are meshed with each other so that one (25) of the elements drives the other. In order to improve transmission conditions within the gear without reducing the toothing module, the corresponding toothings of each of the two elements are multiple, each of them being formed of N coaxial, toothed rings (28a, 28b; 30a, 30b) angularly shifted relative to each other by a fraction of a pitch of the toothing. In the simplest version, each of the toothings is double (N=2), the two rings being angularly shifted by a half-pitch. The invention prevents gearing in areas located relatively far from the line connecting the centres of the toothed elements, thus reducing torque and velocity variations during the lead of a tooth.

Abstract: According to the invention, the time-setting device (18) of the timepiece includes a time-setting lever (62) which carries a coupling device (64) and the pivoting of which is controlled between an uncoupled position and a coupled position corresponding to the time-setting position of the winding stem (22). The coupling device (64) includes an exit pinion (78) which, in the coupled position, meshes with a minute wheel (16), and a plate (90) which is pivotably mounted on the time-setting lever (62) and which is provided with first and second reversion wheels (94, 96) of parallel axes (A8, A9) meshing with each other. An intermediate wheel (60), which is driven in rotation by the winding stem (22) in the time-setting position, meshes with the first reverser wheel (94).

The lever (8) includes a pin (40), which can press against the cams (3, 14) and the surprise-piece (11), and a rack engaged on the pinion (6), such that a radial movement of the lever (8) pivots the trigger wheel (4) in relation to the programming wheel (7).

Abstract: The movement (1) of the watch includes a constant force device (14) inserted in a going rain connecting a spring barrel (2) to an escapement having an escapement wheel and including a third wheel which completes one revolution in several minutes. The input element of the constant force device (14) is the third wheel (12), the output element of said device (14) being a second third wheel (20) connected via gearing to the seconds pinion (38). The second third wheel is secured to a star wheel (26) that only releases the train upstream of the constant force device once per minute, thus forming an independent minutes display because the minute hand (7) jumps forward at each minute. This arrangement minimizes the transmission of shocks between the constant force device and the escapement and can advantageously be combined with a tourbillon (40).

One or several applications of pressure on the pusher (10) activate said corrector (9a) by rotation of the lever.

The time-setting mechanism (16) includes a pull-out piece (50) whose pivoting is controlled by a time-setting lever (30). The pull-out piece (50) controls the sliding of a sliding pinion (36) from a winding position to a time-setting position. The pivoting of an isolating lever (94) is controlled by the mobile part (70) of the striking mechanism (20) so as to cause the sliding pinion (36) to slide from the winding position to an intermediate position, located axially between the winding position and the time-setting position thereof.

Abstract: A calendar watch is arranged to allow time-setting to be carried out without this operation altering the state of the calendar mechanism at the passage to midnight. This mechanism, which is of the instantaneous date type, includes a large lever (2) loaded by a spring and wound by a spiral shaped cam (11) and a click (20) released at midnight by a flexible finger (12) of a 24-hour wheel (10). The mechanism prevents any transmission of movement from the 24 hour wheel to the date wheel set, when they are set in the active position by the winding stem (33) pulled out into the time-setting position of the watch. A pivoting isolator (30), which, in its active position, abuts against the click (20) prevents the click from releasing the lever (2).
