13 1/2”’ | Automatic | Swiss Lever | Small Seconds |

Remarks:

  • First French automatic movement
  • The base movement is the Ultra 602, the automatic module is attached and enlarges the base movement from 10 1/2”’ to 13 1/2”’
  • The bidirectional automatic winding system is based on the same principle as the well-known Magic Lever winding system from Seiko, a variant of the IWC Pellaton winding system. However, Seiko’s Magic Lever was not launched on the market until 1959!
