Abstract

PURPOSE: To improve the operation and design of a watch with time difference correction by making such a construction that normal hands and a calendar display are provided and that an hour hand is solely corrected by the use of the one-directional rotation of the normal hand adjusting operations.
CONSTITUTION: Hour and minute hands 4 and 5 are corrected by the counterclockwise rotations of a crown 1 at its second pulled position 1c, but the correction of the hour hand 4 is made by the clockwise rotations. The rotations of the clockwise rotations of the crown 1 turn a transmission wheel 13 in the clockwise direction. This wheel 13 turns a change wheel 16 counterclockwise and a change lever 15 clockwise against a spring 25 by the engaging pressure against a change large gear 16a. As a result, a brake arm 15a is brought into contact with a minute wheel 17a so that an hour hand 18 is restricted from its rotations. The change wheel 16 born on the change lever 15 is moved, and a change smaller gear 16b leaves the minute wheel 17a so that the larger gear 16a engages with an hour hand gear 19d to turn the same clockwise. Thus, the correction of the hour hand can be accomplished solely with excellent operability.
