Watch Parts Calendar Ring
Product Introduction:
The date ring displays the date, which changes position by increments, driven by the movement. The movement's calendar quick-acting wheel rotates the teeth of the date ring. The date change is typically accomplished by slowly pushing the date wheel at night. A spring-loaded lever engages between the teeth of the date ring, ensuring it stays precisely in place each day and preventing half-moon jumps. The ring typically has 31 teeth, corresponding to the 31 days of the month. The numbers 1-31 are printed or engraved on the ring.
