Abstract (en)
[origin: US2001024405A1] Power reserve indicator mechanism for a timepiece movement of the type provided with a power source formed of a motor spring (26), including a frame (10, 12, 14, 16), a power reserve indicator and a differential gear (30) with a first input (44) connected to a wheel (29) driven in rotation when the motor spring is wound, a second input (42) connected to a wheel (20) driven in rotation when the motor spring is let down, and an output (36a) connected to said indicator, wherein the indicator is capable of covering a given angle comprised between two end positions, defined by a stop (78). According to the invention, an intermediate wheel (32) is inserted between the output of the differential gear and said indicator and includes a resilient member (64) arranged so that the differential gear rotates freely while the indicator remains in abutment.
