Abstract
A timepiece includes a winding stem, a calendar correction transfer wheel that rotates in synchronization with the winding stem in a state in which the winding stem is pulled to a first-step position, a calendar corrector wheel that rotates in synchronization with the calendar correction transfer wheel, a setting wheel lever that supports the calendar correction transfer wheel and the calendar corrector wheel, and a date indicator that rotates in synchronization with the calendar corrector wheel. The setting wheel lever is provided with shaft receiving holes to which the calendar corrector wheel is attachable in a rotatable manner, and the calendar corrector wheel is attached to one of the shaft receiving holes in accordance with the type of the date indicator.
Claims7
A timepiece comprising:
- a winding stem that is allowed to be pulled out to a first position in an axial direction of the winding stem;
- a calendar correction transfer wheel that rotates in synchronization with the winding stem in a state in which the winding stem is pulled out to the first position;
- a calendar corrector wheel that rotates in synchronization with the calendar correction transfer wheel;
- a setting wheel lever that supports the calendar correction transfer wheel and the calendar corrector wheel;
- and
- a calendar wheel that rotates in synchronization with the calendar corrector wheel,
- wherein the setting wheel lever is provided with a first attachment section and a second attachment section, to which the calendar corrector wheel is attachable in a rotatable manner, and
- the calendar corrector wheel is attached to one of the first attachment section and the second attachment section in accordance with a type of the calendar wheel.
