PROBLEM TO BE SOLVED: To provide a device of electromechanical watch, which can determine the moment at which and the direction in which an time indication should be corrected.;SOLUTION: A device for electromechanical watch (1), allowing an electronic control circuit of the watch (1) movement to determine the moment at which and the direction in which an indication showing a magnitude of time has to be corrected, includes a wheel (68), which is driven by the watch (1) movement and which carries means (70, 72) for actuating first and second detection means (46a, 46b) connected to the electronic control circuit. The electronic control circuit deduces, from the moment at which and the order in which the first and second detection means (46a, 46b) are actuated by the means actuating the wheel (68) driven by the watch (1) movement, the direction in which the wheel (68) is being driven by the movement and the moment at which the magnitude of time has to be respectively incremented or decremented.;COPYRIGHT: (C)2011,JPO&INPIT
