American watches

American watchmaking in the catalog is represented by Bulova, specifically the Accutron series made in New York in the 1960s. The 3 references (Accutron Spaceview, Astronaut, and a Bulova Accutron variant) use the electromagnetic tuning-fork movement patented by Max Hetzel in 1953, which regulated timing via a 360 Hz vibrating fork rather than a mechanical balance wheel. The Accutron was the most accurate wristwatch commercially produced before the quartz crisis; the tuning-fork movement shares almost no mechanical DNA with Bulova's current production.
