Hermle HM1161-853-114ST Mechanical Grandfather Clock Movement

The Hermle HM1161-853-114ST is a high-quality German mechanical clock movement designed specifically for traditional grandfather and longcase clocks. Part of the respected Hermle 1161 series, this movement combines reliable eight-day operation with classic chime performance and enhanced silencing functionality, making it perfect for both clock restorations and new clock builds.

This movement is an 8-day, cable-driven design powered by three weights, providing dependable timekeeping for approximately seven days on a full wind. It features a triple-chime mechanism with Westminster, Whittington, and St. Michael melodies that play on the quarter-hour with a full sequence on the hour. The “ST” version includes a selectable automatic night silence feature, which automatically pauses the chime during set overnight hours to minimize disturbance while maintaining regular timekeeping.

Designed for a 114 cm pendulum, this movement delivers the rich rhythm and presence expected in a traditional longcase clock. Solid brass plates and precision gearwork ensure lasting performance and smooth operation. The rear hammer configuration is compatible with standard chime rod assemblies, allowing for straightforward installation in most grandfather clock cases.
