Manual date advance mechanism for a watch

In a calendar watch of the type having a frame, a date ring with internal teeth rotatably mounted in said frame, means for periodically rotatably advancing said date ring, and spring detent means for holding the date ring in position when advanced, the improvement comprising:

• a manual actuator disposed adjacent said frame and having a portion movable with respect to the frame, and
• a date change lever pivotably mounted on the frame, said lever including integral therewith:
• a first integral spring portion having a first contact area cooperating with said frame and biasing the lever to a rest position, a second contact area defined by said lever disposed to cooperate with the movable portion of said actuator to cause said lever to pivot, an integral arm having a tab portion adapted to cooperate with said date ring internal teeth when the lever is pivoted toward an operating position, and a second integral spring portion adapted to flex when said integral arm and tab are pivoted toward an operating position, said lever being arranged to move said tab into engagement with said internal teeth when the actuator is operated, said second spring portion being arranged to hold the tab in position as the first spring portion returns the lever to rest position whereby the date ring is rotatably advanced.
