Problems solved by technology

The watch movement achieves the function of displaying the day of the week by driving the week dial to rotate. However, since the day dial is almost the same size as the calendar dial and occupies a large area of ​​the dial, it needs to consume more energy to drive the day dial, and it is also easy to cause The week dial is stuck, causing the day dial to not rotate normally, which brings a lot of inconvenience to users
In addition, the watch movement has a perspective window on the dial through which the day of the week is observed. However, because the day of the week is too large, the seven week indicators are evenly marked on the day of the week. The interval between them is relatively large. When the week dial rotates, especially when the two-week indicator is replaced, there is a long period of time when the week indicator cannot be seen from the perspective window on the dial, which means that the movement structure is not The function of indicating the day of the week cannot be achieved at all times

Abstract

The invention provides a watch movement with week indication. The watch movement comprises a watch dial, a front cover, a rear cover, a time wheel, and a handle shaft, wherein the time wheel and the handle shaft are arranged between the front cover and the rear cover. A week setting wheel, a week indication fixing shaft, and a week wheel connected with the week indication fixing shaft are also arranged between the front cover and the rear cover. The watch dial is provided with a week indication dial. The week indication fixing shaft is equipped with a week indication pointer. The time wheel is meshed with the week setting wheel. The week setting wheel is meshed with the week wheel. The week indication dial of the watch movement is a stationary dial, and the week indication pointer is driven by a wheel train to rotate so as to achieve the function of week display.

Description

technical field [0001] The invention relates to the technical field of clocks and watches, and more specifically, relates to an electronic quartz watch movement. Background technique [0002] Existing watch movement generally all comprises front cover and back cover and is located at the wheel train between front cover, back cover, and described wheel train comprises hour wheel, minute wheel, second wheel and span wheel etc. The operation of time makes the hour wheel rotate under the drive of the span wheel, so as to achieve the purpose of indicating time. [0003] Chinese patent CN203149277U discloses a watch movement, including a week dial, a week wheel and a week wheel, the week dial is marked with a week logo, and a see-through window is provided on the watch dial to display the week logo, and the week wheel meshes with the week wheel , the week wheel meshes with the week disc, and the week wheel drives the week wheel to rotate, and the week wheel drives the week disc t...
