Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a calendar structure for a watch.

0002

[Conventional technology]

Conventionally, clocks have a calendar structure in which the date wheel and day wheel have the same center of rotation. .

0003

[Problem that the idea aims to solve]

However, the conventional structure faces various problems as typified below. First, for watches with secondary hands, such as chronographs and watches with world time functions. In this case, if the outer diameter of the day wheel is determined by escaping the axis of the secondary hand, the day display position will be in the center of the clock. As the hour, minute, and second hands are placed closer together, the day of the day display tends to overlap with the hour, minute, and second hands placed above, making it difficult to see the day of the day display. do. Also, because the day display and day of the week display are separated, the display balance of the watch is poor. Become. Second, the structure that fixes the dial to the movement was placed outside the outer diameter of the date dial. Therefore, the dial fixing part must be larger than the date dial and the time The meter becomes larger. In addition, watches come in a variety of sizes to meet the various needs of users. However, depending on the size of the watch, the position of the Sunday display and the main plate must be provided. The outer diameters of the two are also different. Therefore, the position of the dial fixing structure is different for each size. As a result, parts and assembly equipment become more diverse. Thirdly, due to variations in parts such as warping of the dial. If the gap between the dial and the day wheel disappears, the day wheel will not be able to rotate and the clock will stop. However, in the conventional structure, the height of the dial was set inside the outer diameter of the date wheel. The gap between the day wheel and the dial must be made larger. did not become. Increasing the gap between the day wheel and the dial will cause the day letter to be placed in the back. , when viewed from an angle, adjacent characters become more visible and the appearance deteriorates.

0004 This invention is intended to solve these problems, and its purpose is to It provides a clock calendar structure that is good and can accommodate watches of various sizes. be.

[0005]

[Means to solve the problem]

The calendar structure of the clock of this invention has a date wheel with day characters and a day wheel with day characters. In the calendar structure of the clock, the rotation center of the date wheel and the rotation center of the day wheel are different, and the date wheel and the day wheel have a portion that does not overlap in a plane. do.
