Abstract
1,159,896. Calendar watches. DAINI SEIKOSHA K.K. Oct.2, 1967 [Nov. 30, 1966], No.44748/67. Heading G3T. A calendar timepiece includes a rotary cam 4 driven by the hour wheel 1 through a pin and slot connection 6, 5, and pivotally connected by the pin 6 to a slidable lever 7 having a guide slot 8 engaging a pin 9, whereby a sudden movement of the lever 7 produced by the cam 4 every 24 hours causes a spring-biased finger 10 pivotally connected to the lever 7 to advance a date ring 16. A day disc 15 is advanced simultaneously with the date ring 16 by a star wheel 14 actuated by a projection F on the lever 7.
