Abstract: A timepiece mechanism for returning the seconds hand to zero, which includes a seconds arbor; a seconds hand; a cam forming a snail cam path which extends in a spiral around the seconds arbor from an inner end to an outer end connected to each other by a radial stop surface; a hammer carrying a cam follower, rotatably mounted about a hammer axis between a disengaged position wherein the cam follower is removed from the cam path and an engaged position wherein the cam follower presses on the cam path; a retaining ratchet system including a toothed wheel and a click which engages with the toothed wheel.

Abstract: Stopping mechanism for a striking mechanism comprising energy storage means including a power reserve transmission wheel set, a strike wheel set comprising a detent ratchet, a main click for the passing strike function and/or a repeater release click, the stopping mechanism includes an uncoupling lever for moving the clicks away from the strike wheel set, by an instantaneous jump of a lever changing the position of the uncoupling lever, when the level of energy of the storage means crosses a predefined threshold, through the cooperation between a finger, driven by the power reserve transmission wheel set, and a jumper returned by a first spring, to bring the finger to bear on a fork of the lever to cause it to pivot abruptly by instantaneously changing the position of a lug with respect to a second spring.

Abstract: A timepiece comprises a chiming device including at least one pivoting toothed sector called rack (1) intended to cooperate with at least one first part (2), driving a second part (3) secured to a pin (32) cooperating with an eccentric (41) for actuating at least one hammer (4) characterized in that the hammer (4) chimes a gong (5) extending substantially in a plane A by being displaced along a plane B which intercepts the plane A of the gong (5).

Abstract: A timepiece includes a movement and a current-time ringing mechanism that includes: an hour cam (40) for providing information on the hour of the current time to an hour sampler, quarter cam (28) for providing information on the quarters of the current time to a quarter sampler, a minute cam (22) for providing information on the minutes of the current time to a minute sampler, wherein the cams are adapted to be driven by the movement, the quarter cam (28) and the minute cam (22) being pivotally mounted and being free relative to each other, and the minute cam (22) including a snail including a single row of 60/N stages and being adapted to be driven by the movement at N revolutions per hour.

Abstract: An electronic timepiece with a time striking device including an electric preliminary signalling means, an electric time striking means, an electric contact means, a time striking selecting means, and a time striking timing circuit in which a timer circuit is included, and preventing mishearing of time striking numbers at a right hour due to the preliminary signalling action making a time striking action predicted in advance.

Abstract: A time striking device for a timepiece including an electric time striking means, an electric contact means electrically controlling the operation of the time striking means, a time striking selecting cam plate synchronously rotating with a time indicating gear train to control the electric contact means in a state capable of closing circuit action at the striking time, a one-minute cam plate synchronously rotating with the time indicating gear train to control the electric contact means in a state capable of closing circuit action at one minute interval, a one-minute control lever transmitting contact point control force of the one-minute cam plate to the moving contact plates of the electric contact means.
