Abstract

PURPOSE: To provide a calendar watch which is equipped with a time difference corrector and which is reduced in size, thickness and cose, by arranging a ring gear around a planetary gear such that the ring gear is in meshing engaement with a calendar advaicing wheel and a time correcting wheel.
CONSTITUTION: Upon correction of an hour hand, the rotational force from a crown is transmitted to an hour correcting wheel 19 to turn a planetary cock 5 so that a minute wheel 7 and a minute intermediate wheel 9 may rotate about a cylinder 4. At this time, the cylinder 4 is restricted during the normal hand turning operation by a second gear 2 so that it does not rotate. As a result, a cylinder 6 is turned by an angle which is determined by subtracting the effects of the rotation angle from the revolution angle of a rear wheel 7a. The number of teeth of those parts is so determined that the rotational angle becomes 30 degrees for the rotation of one tooth of the planetary cock 5. A calendar advancing wheel 17 and a time correcting wheel 18 are in meshing engagement with a ring wheel 14 which is formed with such an internal gear as always mesh with the minute wheel 7. Thanks to such construction, it is possible to provide a calendar watch which is equipped with a time difference corrector and which is reduced in size and thickness.
