Blancpain Tornek-Rayville TR-900 watch front

Blancpain Tornek-Rayville TR-900 Steel, matte black dial

Blancpain, 1964–1966

Why It Matters

The US-Navy-issued Fifty Fathoms, supplied through distributor Allen Tornek so a Swiss dive watch could meet the American Buy America Act. Its dial is signed 'Tornek-Rayville U.S.' ('Rayville' being Blancpain's own reference to its home town of Villeret), with a moisture indicator at 6 o'clock; the radioactivity warning tied to its promethium lume sits on the caseback.
