Abstract: A system (1) for resetting a chronograph is provided with a chronograph counting geartrain (2), which includes a minute counter having a minute wheel set (4), and a seconds counter, which includes a chronograph wheel set (3). The system includes a hammer held blocked by blocking device (11) and displaceable from an inactive position, where the hammer is blocked by the blocking device, and an active position, when the hammer is unblocked, for resetting the chronograph in contact with the various wheel sets (3, 4); a flexible element (10) connected between a reset controller (12) and the hammer for resetting the chronograph, and configured to store energy during a displacement of the controller and before unblocking the hammer blocked by the blocking device to be able, when the hammer is unblocked, to restore this stored energy and drive the hammer to reset the chronograph.

Abstract: The timepiece comprises a timekeeping mechanism and a switching device arranged to switch this timekeeping mechanism between two states. The switching device comprises a movable switching organ and a rotary control organ arranged to be stepwise driven in order to successively occupy a plurality of distinct angular positions about its axis of rotation. The movable switching organ and the rotary control organ respectively support a first magnetic structure and a second magnetic structure arranged so that, in a first angular position of the rotary control organ, a first magnetic force acts on the switching organ in a given direction, and so that, in a second angular position of the rotary control organ, a second magnetic force acts on the switching organ in the opposite direction.

Abstract: A zero-rest device for a timepiece, including first and second control mechanisms, two zero-reset cams, and two corresponding zero-reset hammers configured to cooperate with the cams. The device also includes two hammer springs exerting a pre-stress force causing a hammer to pivot in the direction of its corresponding cam, a winding and release mechanism and a locking mechanism. The winding and release mechanism is configured to wind the hammer springs during a first phase of an actuation of the first control mechanism and to cooperate, during a second phase of this actuation, with the locking means, such that the locking means passes from a rest position in which the locking means holds the hammers to a release position in which the locking means releases the hammers, which come, in each case under the action of the corresponding hammer spring, into the positions thereof of cooperation with the corresponding cam.

Abstract: A chronograph clockwork movement for measuring time includes a control lever actuatable by a first control member for alternatively activating or deactivating a time measurement, clutch elements for driving or not a second timer in response to an action produced on the control lever and selective locking members for locking the second timer in response to an action produced on the control lever. A lever and a hammer for resetting the second timer to zero are also provided. The clockwork movement is arranged in such a way that a user does not feel any difference, while measuring a time, whether the second timer is pre-set or not. The clockwork movement has a structure enabling to activate time measuring by delaying the effective departure of the second timer until an external resetting device controlling the lever is released in the rest position thereof.

Abstract: There is provided a multifunction timepiece wherein the visibility of pointers can be improved, and increases in the thickness of the timepiece can be reduced. This timepiece includes a dial, an hour hand, a minute hand, a pointer, and a movement. The dial has a dial cover and a time display section on the inner periphery thereof. The hour hand is mounted on the time display section and has an hour hand rotating shaft disposed at a different position from the center position of the time display section. The minute hand is mounted on the time display section and has a minute hand rotating shaft disposed at a different position from the center position of the time display section. The pointer is mounted on the time display section and has a pointer rotating shaft. The dimension A from the pointer rotating shaft to the tip of the pointer is greater than the dimension B from the minute hand rotating shaft to the tip of the minute hand. The pointer rotating shaft is disposed at a position away from the hour hand rotating shaft by a distance less than dimension A and greater than dimension B. The movement drives the hour hand, the minute hand, and the pointer.

Abstract: This invention is exemplified by a hammer made in two pieces, a body piece and a lever piece. The hammer is used to return heart cams such as are used in stopwatches and counting devices to the zero position when a button is pressed. The hammer disclosed consists of a pivoted part which coacts with the button and a lever part which is held between the pivoted part and a platen in such a way that it drives the heart cams to zero position when the pivoted lever engages it at one point.
