Hermle 340-020 Mechanical Wall & Mantel Clock Movement – Westminster Chime

The Hermle 340-020 is an 8-day Westminster chime mechanical wall or mantel clock movement, upgraded with bronze bushings in high-wear areas for extended service life and improved reliability.

This movement has been widely used by leading clock manufacturers such as Ridgeway and Howard Miller, and is a trusted replacement choice for many high-quality mechanical clocks. It features a balance wheel escapement, spring-driven power, and bottom-mounted hammers for clear Westminster chimes.

The movement is factory-oiled and ready to install. As with most Hermle movements, the mounting feet may need to be adjusted to fit your specific clock case.
