$175Buy on Amazon
Amazon US, October 2026. Prices change.

A German mechanical movement, a pendulum and weights you pull up once a week. Hermle has made clocks in the Black Forest since 1922, and any clockmaker can service it.

Repairable
Opens with common tools, spare parts are available, and replacement parts work without the maker unlocking them.
Calm
Does not compete for your attention: no notifications, feeds or endless content. Does its job and gets out of the way.
