Abstract: The alarm watch includes a mechanical movement which drives time display means including at least a first hour hand (17) and a first minute hand (13) mounted above a first dial. 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 means for displaying the predetermined alarm time. The alarm time display means include 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 comprised between midnight and midday (AM) or comprised between midday and midnight (PM).

Abstract: The invention proposes a timepiece comprising a repeater striking mechanism (14), the striking mechanism being released either automatically, or manually by a manual control member (22), wherein the striking mechanism (14) includes a release lever (24) fitted with a click (26) which meshes with the teeth of a ratchet detent wheel (28) such that, during automatic release, a release cam causes the release lever (24) to pivot towards the detent wheel (28), characterized in that the release lever (24) is fitted with a toggle lever (104) which carries the click (26) and which is pivotably connected to the release lever (24) during automatic release, and in that manual release is caused by the pivoting of the toggle lever (104) relative to the release lever (24) via the action of the manual control member (22).

Abstract: The invention proposes a timepiece (10) including a striking mechanism (20), and including a control device (28) for activating an element (22) releasing the striking mechanism (20), via a control surface (64) carried by a piston (32), characterized in that a resilient transmission element (68) is arranged between the piston (32) and the release element (22) and in that the travel of the piston (32) includes an active travel, from the rest position of the piston (32) to an intermediate position corresponding to the stop position of the release element (22), during which the travel of the piston (32) is connected to the travel of the release element (22) via the resilient transmission element (68), and a passive travel during which the piston (32) slides against the resilient transmission element (68).

Abstract: The invention concerns a calendar watch 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 means of 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 further includes locking means (30, 40), which prevent 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. Preferably, the locking means include a pivoting isolator (30), which, in its active position, abuts against the click (20) so as to prevent said click from releasing the lever (2).

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 minimises the transmission of shocks between the constant force device and the escapement and can advantageously be combined with a tourbillon (40).
