Abstract

PURPOSE: To realize an automatic calendar watch without damaging the appearance of the conventional calendar watch, by setting a month and a leap year with operations of the crown, etc., while reading numbers of the date wheel as month display.
CONSTITUTION: 12 convexes 17aW17l are provided in the lower part of date wheel 1, and a month is set by these convexes. 4 convexes 18aW18d provided in the lower part of date wheel 1 correspond to the 20thW23rd of a date display respectively, and a leap year is set by these convexes. When day advance pawl 2 starts day advance at the end of the month, switch 16 is brought into contact with convexes 5aW5c of the date wheel, and signals of the 29thW31st of a month are sent to a calendar decision circuit to decide the data. Further, when further day advance is required, a driving current is sent to coil 14, and date weel 1 is caused to advance by day advance date feed pinion 11.
