A timepiece has a second hand, a minute hand and an hour hand which are rotationally driven by a gear train under control of an electromechanical transducer. The transducer has a plastic coil frame on which is wound a coil and electric drive signals are applied to the coil in response to which the transducer produces a rotational output for driving the gear train. A hand stopping device is formed integrally with the coil frame and functions to temporarily stop the rotational movement of the gear train to thereby enable setting or correction of the position of the second hand. The device comprises a flexible arm formed integrally with and projecting from the coil frame, the arm having a manually operated portion in the form of a button which, when actuated, resiliently flexes the arm from an inoperative position to an operative position, and an interlocking portion operable when the arm is flexed to its inoperative position to releaseably interlock with a gear of the gear train to thereby stop the rotational movement of the gear train.
A hand stopping device for a timepiece having a second hand, a minute hand and an hour hand driven by a gear train which is driven by an electromechanical transducer, the improvement comprising:
In a timepiece having an electromechanical transducer which has a coil wound on a coil frame for rotationally driving a gear train to thereby rotationally drive a second hand, a minute hand and an hour hand:
