Abstract
A time measurement device includes a first motor (1300) for indicating standard time, a second motor (1400) for indicating a chronograph, a generator (1600) which generates driving power for driving the first and second motors by converting mechanical energy into electrical energy, and a zero reset mechanism (1200) for mechanically resetting the chronograph to zero. A compact time measurement device, operable from a low power, is thus provided.
