Abstract

The spring device includes an indicator needle (6) indicating the reserve of energy stored in the wound spring. The indicator is driven by the spring box (2) of the mechanism whilst the spring is unwinding during the normal operation of the watch. The indicator is then moved by the winding ratchet mechanism during the winding operation. The drive from the spring box is effected by means of a pinion with a tube (5) held by friction on the axis of a pinion linked to the needle by a drive train. A sliding pinion (3) slides in a groove and is driven by the ratchet during the winding operation. USE - Indicating state of spring of manual or automatic watch.
