Family: 39018,000 vph (2.5 Hz)
The FEF 390 is an automatic movement used by Tudor. Based on a Fleurier Ebauches caliber, it powered early Submariner references 7922 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.
