The ETA 738 is a mechanical watch movement with a manual wind function and a sub second indication. It was used in watches manufactured around 1946. However, it is unclear whether the ebauches (movement blanks) were produced by A Michel or Felsa, and there is limited information available regarding the differences between the 390, 392, 393, and 398 movements.
The ETA 738 features the following functions:
- Manual Winding
- Sub Second
