Hermle 451-050/114DB Mechanical Grandfather Clock Movement

The Hermle 451-050/114DB is a high-quality German mechanical clock movement engineered specifically for traditional longcase and grandfather clocks. This 8-day mechanical movement delivers reliable timekeeping with a classic bim-bam striking sequence, combined with a decorative dial-back feature that enhances visual appeal and finishing detail in open-dial or glazed cases.

This movement uses a weight-driven, cable system to ensure consistent power delivery and smooth operation for approximately eight days on a full wind. It features a bim-bam strike pattern, producing a single strike at the half-hour and a two-tone strike on the hour, engaging three hammers on a set of chime rods or gongs for a rich, traditional sound.

Designed for a 114 cm pendulum length, the 451-050/114DB offers classic performance with a dial-back aesthetic that suits clocks with visible movement or decorative backing panels. Built with robust brass plates and quality German engineering, this movement delivers durability, accurate operation, and long service life.
