PURPOSE:To improve the design with a lessened thickness by minimizing the movement of a member sliding on a stem shaft with a hand turning member separated from a calendar correction member to increase the space of members to be arranged. CONSTITUTION:A stem 1 has a base section 1a and a tip section 1b supported with a side plate 2 and a day back holder 3 through a shaft. The tip 5b of a spring section 5a formed on a stem holder 5 fixed with a screw 4 arranged on the top of the day back holder 3 is engaged with a groove section 1c formed on the stem 1 through an opening 5a of the day back holder 3. A cylinder wheel 6 is supported rotatably on the shaft of the stem 1. This separates a hand turning member from a calendar correction means to reduce the movement of a member sliding on the stem shaft for a larger space of members arranged thereby improving the design of a timepiece with a lessened thickness. |
