Abstract
PURPOSE: To reduce the load at the calendar feeding, reduce the current consumption of the watch and prolong its battery life by providing a positive motion cam cooperating with the drive means of a calender wheel and oscillating a defining means having spring characteristic.
CONSTITUTION: When the time comes to around 0:00 AM, the date feed pawl 3c of a date feed wheel 3 enters the locus of a date wheel 8 and a day feed pawl 4 also enters the locus of a daily star 6. Further as the time passes by, the dowel 5a of a defining lever 5 is directed from the groove 3a of the date feed wheel 3 into 3b, then the defining lever 5 begins to turn right, as a result of which the defining levers 5b, 5e part go away from the date wheel 8, daily star 6 respectively, thus reducing the load when the date wheel 8 and daily star 6 are driven by the date feed finger 3c and day feed finger 4. When the calendar feed for one day is completed, the dowel 5a of the defining lever 5 enters the groove 3a and the defining lever oscillates and returns to the original position.
