| 摘要 |
The invention relates to a device indicating run reserve for timepiece motion comprising a power spring (14), a run reserve indicator displaceable between two end positions, a differential gear (18) and a intermediate mobile (32) comprising first and second parts cinematically connected to the differential gear (18) and to the indicator, respectively, and an link unit connecting said parts which rotate together when the winding of the spring (14) is disposed between the end positions thereof. Said link unit comprises a friction mechanism which is arranged in such a way that the first part is frictionally movable with respect to the second part when the indicator attains the first end position thereof and an elastic element which is disposed in such a way that it is cocked when the indicator attains the second end position thereof by displacing the first part with respect to the second part. |
