Abstract
1373838 Date indicating CITIZEN WATCH Co Ltd 17 Feb 1972 [17 Feb 1971] 7308/72 Heading G3T A calendar correction mechanism for a timepiece operates when a winding stem 2 is in a correcting axial position to change the date when rotated in direction A, Fig. 4, and the day when rotated in a direction B, Fig. 5. Date correction is effected Fig. 4, by teeth 7b' of a wheel coupled to the stem 2 engaging a portion 18e of a pawl member 18 to rotate it against the action of an arm 18d. The teeth 13a of a date dial 13 are moved by a pawl member 18b to commence a date change which is completed by the action of a jumper lever 16a. Day correction is effected Fig. 5, by teeth 7b' rotating a member 18 to cause a pawl 18c to initiate a step by a day star-wheel 15a which is completed by a jumper lever 16b. In an alternative arrangement, for use with a two-language calendar facilities are provided by language selection and corresponding half-step correction.
