10 WA

Calibre 10 WA is a modular alarm movement from Wittnauer produced in the 1950's.

Unlike integrated alarm movements from Vulcain and Jaeger-LeCoultre, Wittnauer added an alarm module to an existing movement, the Longines-based Cal. 10.

The Wittnauer alarm calibre is notable for its unique features

  • The alarm module includes its own barrel in the module rather than the main calibre
  • The alarm is wound and set using a rotating bezel rather than an added crown or pusher




Production period:

  • 1950's
