Solar orientation and sunrise and sunset display mechanism of watch

Abstract

The invention discloses a solar orientation and sunrise and sunset display mechanism of a watch. The mechanism comprises a driving part, a command control part and a function display part. The driving part is a power input end and drives the command control part, and solar orientation and sunrise and sunset are displayed by the function display part. The beneficial effects are as follows: visual movements of the sun are displayed effectively since a horizon indicator panel moves relative to a sun disc, and the time of sunrise and sunset is automatically adjusted along with changes of dates; the mechanism is simple and reliable, is relatively low in machining difficulty, and exhibits good universality; the entire mechanism is relatively independent, occupies little space, can be adjusted and calibrated independently, and can be mounted and dismounted as a whole; a mechanism module can be loaded to a perpetual calendar movement, is also suitable for a non-perpetual calendar movement, is greatly improved in adaptation, and becomes a function module quite high in universality; and in particular, components of the mechanism can be correspondingly replaced on the basis of different latitudes where users are located to meet usage demands of different latitude regions in the world, and exhibit good interchangeability.

Description

technical field [0001] The invention relates to a watch mechanism, in particular to a display mechanism for the real-time sun azimuth and sunrise and sunset of the watch. Background technique [0002] Human beings' understanding of time originates from the observation of celestial bodies. The concepts of day, month and year come from the rotation of the earth, the revolution of the moon around the earth, and the revolution of the earth around the sun. Therefore, chronometry can be said to have developed from astronomy. Due to the complex movement of celestial bodies, in mechanical watches, the astronomical display is usually used as a complication to provide additional time information. [0003] As the central celestial body of the solar system where human beings live, the sun has always held a lofty position in people's hearts. The sun is closely related to the daily life of human beings. Whether it is farming, production or work and rest activities, it is inseparable fro...

Problems solved by technology

This method can better display the solar time and the coming and going of the sun. However, this method is still a pointer type. If the pointer indicating the solar time is replaced with a sun pattern, the sun is below the dial after sunrise and rotates clockwise. Actual discrepancy

Moreover, the mechanism is very complex and extremely difficult to implement

So far, there is no mechanical watch that can display the apparent movement of the sun, and use the horizon to display the sunrise and sunset, and the sunrise and sunset times vary according to the date
