Catalogue description

Dealer description — S.Song Watches

Debuting just a year after the iconic Rolex Submariner in 1954, the Tudor Submariner stands tall as one of the most iconic and sought-after vintage dive watches of all time. Merging Rolex's practical and robust designs with Rolex externals and a third-party movement, Tudor met the need for a high-quality tool watch for the everyday man, and the Submariner stands tall as perhaps their most iconic offering of all time. Having gone through several iterations, the ref. 7928 introduced crown guards and a more modern case profile than that used on the older variants. Offered here, I have a completely original example with a stunning black gilt dial complete with a chapter ring along its periphery and creamy lume on its hour markers and hands. It doesn't stop there, however, as this example also features a Rolex-signed caseback and crown. Powered by the Rolex-customised Fleurier cal. 350 known as the Rolex cal. 390, the Tudor ref. 7928 combines the very best of vintage watch collecting into one attractive package. With its distinctive charm and immaculately preserved condition, this Tudor Submariner ref. 7928 stands as one of the finest examples offered on the market today. Fitted with the black "long 5" aluminum bezel insert to match its black dial, this monochromatic beauty will undoubtedly serve as a worthwhile addition to any collection.

Historical context

Modern Mechanical Horology (1945 – 1969)

Tool watches for divers, pilots and astronauts; electric watches anticipate the electronic age.

The classic era of the mechanical wristwatch: dive watches, chronographs for motor racing and space flight, GMT watches for jet travel, slim dress watches, automatic calendars, and the rise of Japanese manufacturers alongside Swiss, American, German and Soviet industries.

Atlas type guide

Dive and water-resistant watches

Keeping water and dust out of a wristwatch was a long-standing challenge. Rolex's screw-down Oyster case (1926) and Omega's Marine (1932) were landmarks; in the early 1950s Blancpain's Fifty Fathoms and Rolex's Submariner defined the professional dive watch with rotating bezels for timing dives, luminous dials and high water resistance. The ISO 6425 standard (1982) later codified what a 'diver's watch' must do.

Dive watches became icons of post-war design and exploration, and their evolution — helium escape valves, ceramic bezels, saturation-diving depth ratings — records the history of underwater work.

What to look for

  • Unidirectional or bidirectional rotating bezel with minute markings.
  • Screw-down crown and case back; depth rating printed on the dial.
  • Luminous hands and markers (radium before c. 1960, tritium c. 1960–1998, then Super-LumiNova).
  • Reference numbers on the case between the lugs or inside the back.

Dating clues

  • Screw-down Oyster cases: from 1926.
  • Professional dive watches: from 1953.
  • Tritium 'T' marks on dials: c. 1960–1998.
