Abstract: A timepiece including at least analogue time display device, and an AM-PM display device for displaying day-night information in the dial of the timepiece. The AM-PM display device includes at least two apertures made in the dial of the watch, a rotating display disc bearing at least one first series of inscriptions corresponding to the day and at least one second series of inscriptions corresponding to the night, these two display series being disposed on at least two concentric circles, and a drive mechanism arranged so as to automatically and alternately bring the first series of inscriptions inside a first aperture and the second series of inscriptions inside a second aperture by rotating the display disc.

Abstract: In an exemplary embodiment of a timepiece of the present disclosure, the timepiece comprises a case, a crown extending from the case, a first pusher extending from the case and positioned relative to the crown, a first crown tab positioned between the crown and the first pusher, the first crown tab configured to at least partially surround the crown, a first pusher element extending from the case, the first pusher element configured to at least partially house a first end of the first pusher, a second pusher extending from the case and positioned relative to the crown, a second crown tab positioned between the crown and the second pusher, the second crown tab configured to at least partially surround the crown, and a second pusher element extending from the case, the second pusher element configured to at least partially house a first end of the second pusher.

Abstract: An electronic timepiece has a date wheel for undergoing rotation in accordance with movement of an indicator to change a display state of a date display, a 24 hour wheel driven to undergo one complete rotation each 24 hour period in accordance with movement of the indicator, and a contact spring connected to the 24 hour wheel for rotation therewith. A circuit board has first and second electrode patterns electrically connected to each other by the contact spring. A switching circuit changes a voltage level of the first electrode pattern to a first voltage level. A detector outputs an initializing signal corresponding to detection of termination of an operation for interchanging a battery of the electronic timepiece or for correcting time.

Abstract: The date disc correction mechanism (3) of this time-piece comprises a control stem (7) movable between at least two axial positions, and on which a sliding pinion (9) and a correction pinion (17) are mounted. The sliding pinion exhibits at least one spur (28) provided in order to come into engagement with an opening (25) formed in the correction pinion in one of the axial positions of the stem (7) so as to render the correction pinion fixed in rotation with the sliding pinion (9).

Abstract: The setting mechanism of a watch includes a winding stem and a clutch wheel which can be moved selectively either rotationally or axially by said winding stem for control of one or more setting levers or wheels. The setting levers or wheels are disposed on the opposite side of said winding stem from the dial plate of the watch, thereby making it possible to center the winding stem in the thickness direction of the watch and to reduce the over-all thickness of the watch.
