Seiko 5M42-0L10
The Seiko 5M42-0L10 movement is a mechanical movement with a Breguet hairspring. It is equivalent to the Aurore-Villeret 120, Bulova 6AH, FHF 120, and their various derivatives. The interchangability data for these calibres are inconsistent across different movement registers. There are design details in the Bulova calibres that are not found in the FHF calibres, suggesting that the ebauches may have originated from Aurore-Villeret. The Seiko 5M42-0L10 movement features sweep seconds and was used during the period of 1940-1947.
The Seiko 5M42-0L10 features the following functions:
- Mechanical Movement
- Sweep Seconds
