Catalogue description
Dealer description — Craft & Tailored
The Tudor Submariner ref. 7928 was first introduced in 1960. The ref. 7928 is like the little brother to the Rolex 5513/5512 references as they share a lot of the same exact parts and although different they do share a lot of similar design elements. An interesting fact is that the Rolex Submariner and the Tudor Submariner were actually developed at the same time and launched just a few months apart from each other. The Tudor Submariner ref. 7928 is just as handsome as the big brother Rolex 5512/5513 references but again possesses a unique charm and feeling that is uniquely Tudor! The Tudor Submariner Reference 7016/0 was introduced in 1968 with quite a few changes compared to its predecessor reference 7928. Not only did the 7016/0 bring us the famous "Snowflake" dial and hands configuration, and the movement was upgraded to an ETA 2483, but the case was changed as well. The early 7016/0 Tudor subs feature was is known among collectors as a Semi-PCG or semi pointed crown guard case, this is in reference to the very different crown guard shape produced for the 7016/0 in the early half of 1968, the crown guards are not necessarily "pointed" like early PCG cases for both Rolex and Tudor, however, they do have a much more slender appearance to the more modern style seen after and are sloped up to a smaller rounded point, hence the Semi-PCG name. These cases are only produced in a short range of serial numbers as the Semi-PCG case production was short-lived and was replaced at the end of 1968.

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.
