摘要 |
The invention concerns a movement for a timepiece whereof one mechanism, driven by the finish clockwork (1) of the movement, acts periodically, typically every six minutes, on an indicator member bearing the representation of a shooting star (25), via two coaxial mobiles (4, 10) linked to each other through a hairspring (7). The first mobile is continuously driven by the finish clockwork, while the second mobile is maintained fixed by locking means (15, 16, 17, 18) and intermittently released under the effect of a cam (6) integral with the first mobile. A kinematic link (23) transmits the imperceptible movements of the second mobile to the disc (24) of the indicator member. Said disc is advantageously made of sapphire and arranged in front of the disc (26) of a mechanism displaying phases of the moon. |
