Abstract

A watch comprises a first motor (2) for driving a time display (4), a second motor (23) for driving means (20) for numerically indicating the day of the month, a perpetual-calendar circuit (30), a first transmission circuit (40), a non-volatile memory (41), a second transmission circuit (42), and a detection circuit (43) for generating a signal (S43) when an energy supply cell is being inserted to energize the circuits. The calendar circuit includes counters (31, 32, 33) generating a calendar signal (S30) representative of the date. This signal is periodically transferred to the non-volatile memory by the first transmission circuit in response to periodic signals (Sx, Sm, Sa). The date at which the watch stops at the end of the cell's life remains memorized in the non-volatile memory and in the day of the month indicating means. When a new cell is inserted, the signal representative of the date at which the watch stopped is transferred from the non-volatile memory to the calendar circuit by the second transmission circuit in response to the signal (S43) generated by the detection circuit.
