Catalogue description

Dealer description — Oliver & Clarke

The Submariner, namely those produced by Rolex, has long been considered the cream of the crop when it comes to watch collecting as a whole. Possibly the most iconic watch ever produced, the Submariner has long standing utilitarian roots that span decades, and everyone who’s anyone has been spotted wearing one. However, if you look deeper into the Submariner line, you may find a less known but just as incredible model manufactured by Tudor. The Ref. 7928 that we have here dates to circa 1959 and in known as an 'Eagle Beak' for the unique shape of the crown guards found on a handful of Professional models from this era. Simply put, this has the be one of the finest examples to come to market in recent memory. Completely unpolished, it touts thick lugs with prominent chamfers and those characteristic crown guards reminiscent of the beak of an eagle. The bezel assembly, also unpolished, houses a clean black 'fat font' insert with a patinated pip. Inside, the glossy black dial exhibits patina from age, while retaining nice 'gilt' text and a beautiful chapter ring on the outer edge. The luminous plots also show patina from age and remain largely intact with a nicely matching handset. It comes fitted to a correct albeit later 'rivet' Oyster bracelet with a blade clasp. For many of us, this is what vintage is all about: subtle details, honest condition that tells a story, and uniqueness in wear/patina. This one embodies all of the above! And that case...

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.
