Starry sky moon phase display mechanism in watch

Abstract

The invention discloses a starry sky and moon phase display mechanism in a watch. The mechanism comprises a double-calendar wheel, and a moon phase display part and a starry sky display part which arepackaged into one part, wherein the double-calendar wheel is respectively engaged with the moon phase display part and the starry sky display part to drive the moon phase display part and the starrysky display part to rotate. The mechanism is advantaged in that 1, the double-calendar wheel simultaneously controls and drives star sky real-time indication and moon phase indication so that an ornamental value and artistry of the watch are increased, universality of structural parts is good, process difficulty does not need to be increased, and the occupied space of the watch is small; 2, starrysky and moon phase functions appear in a module form, transmission connection is completed through a universal double-calendar wheel in the watch, universality is high, personalized customization andflexible production of the watch are convenient to realize, and convenience is provided for assembly and maintenance of the watch in the future; and 3, moon phase display is located at different positions of a dial plate according to different positions of the moon at the same time every day.

Description

technical field [0001] The invention relates to a celestial body display mechanism of a watch, in particular to a display mechanism capable of simultaneously displaying the relative positions and shapes of starry sky charts and moon phases. Background technique [0002] Patent CN193965809U discloses a display mechanism with a rotating star map on the dial surface. The star wheel rotates in a cycle of one year to display the changing position of the star sky. However, only the star map display will make the watch lack dynamic elements, because the cycle is too long It will cause the user to have the illusion that the star wheel does not move. [0003] Patent CN196788560U discloses a moon phase display mechanism of a watch. The moon phase disc jumps at a fixed period, and the real moon phase of the day is displayed in the window, but only the moon phase display in the window will make the dial not full enough, and the window is fixed, and the moon cannot be seen. The relative...
