Cal. 7768 is a hand-winding cam-switching chronograph movement with date wheel and moon phase. Closely related to the popular Cal. 7750, and hand-winding Cal. 7760, Cal. 7768 adds a moon phase indicator in place of the 12 hour counter. The moon phase is unusual for in the 7750 family in that it uses the day wheel for a larger moon indicator instead of the small subdial moon found other movements.
