AS 373 old

25 views

10 1/2”’ | Hand Wind | Swiss Lever | No Seconds |

Remarks:

  • Shown in the Ebauches SA catalog with setting lever spring. This movement here has none, hence the unofficial designation “old”. AS often had the same caliber number, first without and later with setting lever spring.
  • The AS 373 with setting lever spring is presented here: AS 373
  • In this case, the model number 373 in the Swiss Official Gazette of Commerce matches the manufacturer’s caliber designation. This is usually not the case.
