PURPOSE:To realize the common use of a basic movement between a plain watch and a watch with calender, by setting the pull-out step number of a crown by varying the form of a setting lever. CONSTITUTION:In the case of a plain watch, the projected part 30a of a setting lever 30 is fitted to the recessed parts 25c and 25d, and a setting stem 20 has a 2-step pause position. The part 30a is never fitted to a recessed part 25b at the actuating position since it has a projected part 30b. In the case of a watch with calendar, the winding stem 20 has a 3-step pause position by using a lever 30 having no projected part 30b. |
