As a mechanical watch fan and collector (10 and more), I find this watch (Max Bill Automatic - from Junghans) absolutely fascinating. Timeless Bauhaus design, now copied endlessly. This is the OG.

Max Bill's original Kitchen Clock designed for Junghans (1956-57) is in the MoMA (https://www.moma.org/collection/works/139247 )
