All of our grandmother movements are Hermle weight driven movements that come complete with hands, polished brass weight shells and weights, chime rods, a standard wooden pendulum rod with polished brass disk, and all mounting hardware. They feature an automatic escapement which makes the regulation of the beat an easy operation. Also, the chimes can be silenced by a lever at the 3 o'clock position. The cable wound movement also features an automatic night shut off.

Hermle 8-day Triple Chime Cable Drive with automatic night shut off.

This movement has the same plate size as the Grandfather clock movement HC3 but takes a shorter pendulum to fit a Grandmother size clock. A lever at the 3 o'clock position can change the rich tone of Westminster to two other melodies: Whittington and St. Michaels. A brass rod, which attaches to automatic night shut off gear can be pushed up or down to engage or disengage the night shut off feature. Once activated, the clock will not chime from 10 o'clock at night to 7 o'clock in the morning. The movement also features a second hand just below 12 o'clock.
