Family: 390
The FEF 390 is an automatic movement manufactured by Tudor and introduced in 1958. Based on a Fleurier Ebauches caliber, it powered early Submariner references 7922, 7923, and 7924. Production has been discontinued. This was a sourced movement rather than an in-house caliber, reflecting Tudor's practice during this period of using external ébauches for its dive watches.
