Abstract: Device (400) for selecting a clock function from a rewinding function and m correction functions, m>1, comprising a control member (3), notably a staff, able to select the rewind function by movement of the control member in a first direction and to select sequentially one function from m correction functions by movement of the control member in a second direction.

Abstract: Lever (6) comprising at least a first element (61) for guiding in rotation of a first wheel (1), at least one friction element (62) which is designed to co-operate with an at least substantially cylindrical portion (10c) of the first wheel, and at least one resilient element (63), which is designed to return resiliently the at least one friction element to a state of co-operation with the said portion of the first wheel, notably in contact with the said portion of the first wheel.

Abstract: Control mechanism for a timepiece movement, including, in a housing in a main plate, a control stem that is movable in a longitudinal direction and including a groove cooperating with a stud comprised in a pull-out piece for actuating the pivoting of the pull-out piece on the main plate, this pull-out piece is held in position by a jumper spring, and the mechanism including a bridge cooperating with the main plate to confine the stem, and this bridge includes a housing in which there is a movable limiter piston, arranged to abut on one end of a trunnion comprised in the pull-out piece under the application of a force in a transverse direction substantially orthogonal to the longitudinal direction, to allow the release of the stem after a given travel of the limiter piston.

Abstract: The mechanism for transmission of axial and rotative movements between two portions of a stem with offset axes, includes a movable assembly movable axially. The section portion of the stem carries a second pinion and is pivoted on said movable assembly but it is axially secured to, this movable assembly. The first portion of the stem is pivoted on the movable assembly but axially secured to this latter and is secured to a first pinion, one or an uneven number of reverser(s), pivoted on the movable assembly kinematically connects the first pinion to the second pinion.

Abstract: The push-button mechanism includes a lever (11) which pivots on a plane support (2), and includes two other pins (14, 16) arranged in a triangle with respect to the stud (12), and a second member (20) including a substantially U shaped cut-out portion (21) delimiting a base (22), and first and second arms (28, 32). The base (22) supports guide means (23) which slide along a guide ramp (3) and at least one control means (24) for a function to be activated (5, 6). The first rigid arm (28) is rotatably mounted on a first pin (14) of the lever (11) and the second flexible arm (32) has at its free end (33) a notch (34) acting as support for the second pin (16) in the inactive position, said notch (34) being extended by a beak shaped tip (36) having an external edge (38) oriented towards the exterior of the U shaped cut-out portion (21) against which the second pin (16) slides compressing the flexible arm (32) and producing a clicking by passing from one position to the other.

Abstract: An arrangement for setting the minute hand of a timepiece which has at least minute and second hands 29, having a setting stem 1 which can be moved axially out of a normal position into a setting position. In this case, upon movement of the setting stem 1 out of the normal position into the setting position, a zero setting drive of the second hand 29 can be driven such that it moves the latter into its zero position and the seconds stem 28, which bears the second hand 29, can be driven via a seconds-display drive mechanism 30 of the movement mechanism of the timepiece. The seconds-display drive mechanism 30 has a blocking device which can be actuated, by virtue of the setting stem 1 being moved in the direction of the setting position, such that the seconds-display drive mechanism 30 is blocked before the second hand 29 is moved into the zero position.

Abstract: An arrangement for setting the minute hand of a timepiece which has at least minute and second hands 29, having a setting stem 1 which can be moved axially out of a normal position into a setting position. In this case, upon movement of the setting stem 1 out of the normal position into the setting position, a zero setting drive of the second hand 29 can be driven such that it moves the latter into its zero position. By virtue of the setting stem 1 being moved out of the normal position in the direction of the setting position, it is possible to initiate operation of a spring-force-operated drive by means of which the zero setting drive of the second hand 29 can be driven such that it moves the latter into its zero position.

Abstract: Analogue display timepiece comprising a mechanism for hand setting via direct action of a pull-out piece (4) on an intermediate wheel (10) mobile along a shaft perpendicular to the general plane of the plate (P) of said timepiece between at least one neutral position in which said intermediate wheel (10) is disengaged from a motion-work wheel (20) and a hand setting position in which it meshes with said motion-work wheel (20), said intermediate wheel (10) being moved from one position to the other by translation of a hand setting stem (1) by being drawn at its base (12) by resilient means (15) into the hand setting position and being brought into a neutral position by an arm (7) of the pull-out piece (4) acting directly on the head (11) of the intermediate wheel in order to oppose the resilient means (15).

Abstract: Correction mechanism consisting of a corrector (K) mounted so as to pivot (1) and provided with a roller-pin (P) pressing against a rod (T) under the action of a spring (Kr). The rod (T) has two parts (Ta, Tb) of different diameters. When the roller-pin (P) is pressed against the large-diameter part (Ta), the corrector (K) is moved away from the wheel (R2) to be blocked or to be driven. A pull on the rod (T) enables the roller-pin (P) to move onto the smaller-diameter part (Tb), this having the effect of causing the corrector (K) to work in a negative manner. Such a corrector is advantageously used by itself or with a similar corrector in a double-faced watch.

Abstract: A hand adjustment structure for a wristwatch which has a spur gear structure disposed intermediate the minute and the hour gears of the watch includes a crown gear structure on one side of the spur gear disc for engagement with the pinion of a time setting shaft by which the spur gear structure can be rotated and together therewith the watch's minute and hour hands radial projections are stamped axially out of the spur gear disc in a circular array so as to form the crown gear structure integrally with the spur gear disc.

Abstract: The time setting intermediate wheel 20 comprises both a wheel 20a which engages with the sliding crown wheel 8 when the crown wheel is slid in to the illustrated engaged position, and a pinion 20b which engages with a wheel of the watch gear train, for example the minute wheel 26a of the motionwork wheel 26.

Abstract: A battery operated time piece including a movement casing, slip means for the minute wheel, terminal members, correction means for the minute wheel, a sounder, an adjuster to control the level of the sounder. All these elements are of simple structure which eliminates the need for troublesome assembly procedure.

Abstract: A second hand correction device comprising a second hand correction member which may be moved manually in inward and outward directions and in forward rotation and reverse rotation directions and a cam wheel, having a plurality of cams, which is fixed to the second hand axis. The second hand correction member is moved in such a direction as biased under an engagement with the cam wheel when the same is lowered, and engages with the cam at the rear half of its stroke. Subsequent lowering operation of the second hand correction member will cause the rotation of the cam wheel and thereby the second hand will be rotated by a specified angle to enable a repetitive continuous correction for the second hand.

Abstract: A watch having epicyclic speed reduction gearing to drive the hour hand from the minute hand with quick hour setting device to change the hour hand without affecting the timekeeping function being measured by the minute hand.
