| 摘要 |
The invention concerns a power reserve indicator mechanism for a timepiece of the type comprising: a mainspring (14), a power reserve indicator moving between two end positions, a differential gear (18), and an intermediate wheel set (32) including first and second parts respectively kinematically coupled to the differential gear (18) and to the indicator and a coupling member coupling said parts, which rotate conjointly while the winding of the mainspring (14) is comprised between its end positions, Said coupling member includes a friction mechanism arranged such that the first part can move with friction in relation to the second when the indicator has reached its first end position, and an elastic element arranged so as to be able to be cocked when the indicator has reached its second end position, by the movement of the first part with reference to the second part.
