Gear train of an electronic timepiece |
| 摘要 |
The size of an electronic timepiece is decreased through improvement in the design of the gear train. The improvements are directed primarily to the number of teeth on the wheel attached to the seconds hand and the relation of the pitch interval of this wheel to that of the wheel which drives the seconds wheel.
