7 Days Week Clock Movement

Description
PATENT PROTECTION
This clock part, created and patented by Young Town, features an innovative design. Like other standard clock movements, week clock movements help quartz clocks display standard time with second, minute, and hour hands. However, what makes this module so special is that 7-day clock movements can even show the day of the week using an additional indication hand.

The day-of-the-week pointer moves one step per day.
