Problems solved by technology

Generally, calibration or zeroing can be achieved by adjusting the hands or rotating the dial. Due to the mechanical height indication, the rotation of the hands is directly transmitted from the sensor, so if it is to be realized, the structure is very complicated or may destroy the normal height conduction
Therefore, there is a lack of a simple and stable dial calibration implementation structure, and it is also necessary to ensure that the dial is stable when calibration is not required

Abstract

The invention provides a dial calibration clutch device structure and a watch. The position of a marble clamp spring is adjusted through a clutch handle head, so that the clutch structure which can control an adjusting gear in a neutral position and drive the adjusting gear to rotate so as to drive the dial plate to rotate is realized. Through the dial calibration clutch device structure, an altitude display dial can be conveniently and manually rotated for adjustment when calibration is needed, and rotation of the altitude display dial is locked when calibration is not needed, so that the stability and accuracy of measurement are guaranteed, the structure is simple, the machining process is convenient, and user operation is convenient.

Description

technical field [0001] The invention relates to the field of watches, and more specifically relates to a dial calibration clutch device structure and a watch. Background technique [0002] In some special operations or sports, in addition to the conventional time display, the watch also needs other auxiliary functions, such as compass, altitude display and other functions. Especially for the display of altitude, most of the existing watches are electronic. Generally, the atmospheric pressure data is collected through the pressure sensor, and the collected atmospheric pressure data is converted into the corresponding altitude information, which is then displayed by dial numbers or pointers. The accuracy of this function is more accurate through electronic means, but electronic products are prone to software crashes, power outages, and shutdowns in some harsh environments, such as high altitudes. In these application environments, if the watch fails, or the display Failure to...
