Date indicator disk maintenance assisting device for e.g. wrist watch, has locking units maintaining jumpers in locked position out of correction periods of date indication and released in correction phase of indication to liberate jumpers
The device has locking units i.e. locking levers (52, 52'), maintaining jumpers (50, 50') in a locked position out of correction periods of date indication. The locking units are released in a correction phase of the date indication for liberating the jumpers. The locking units are spaced from a locking position by an activation unit (54). A spring (51) and another spring assure maintenance of respective locking units. The locking units are maintained against toothed wheels by arms (51b, 51b').
