Catalogue description
Dealer description — Oliver & Clarke
Sound a little bit like... Tudor? That would be a correct statement. Interestingly, or rather perplexingly, The Oyster Watch Co. was founded just two years after Tudor by the same person: Hans Wilsdorf. Like Wilsdorf's other brands, the Oyster Watch Co. designs often echoed the styles of one another, usually sharing names, parts, and even reference numbers. The piece that we have here, an Oyster Junior Sport, is a 'mid size' Oyster model that, as its name suggest, utilizes a water-resistant Oyster case along with a manually-wound movement, and nothing else. No frills — purely a functional timekeeping device. Dating to circa 1940, this example is offered in strong overall condition. The 30mm case remains thick and symmetrical, with a correct smooth steel bezel, and a screw-down crown. The silver dial within shows a light and uniform patina across the 'brushed' surface, with excellent black printed 'Arabic' indices, 'railroad' minute track, and text. The Radium luminous plots exhibit uniform darkening and the handset has been previously color-matched with Tritium and presents beautifully. It is believed that these Junior Sport models in particular were sold in the Canadian market, and were often found at military PXs. They were popular among soldiers in WWII for their water-resistance, robustness, and simplicity. All things considered, like many Oyster models from Rolex and Tudor in the 1940s-1950s, this piece remains not only slept on, but flat out unknown to the greater collecting community.
Historical context
Golden Age of Mechanical Watchmaking (1900 – 1945)
The wristwatch displaces the pocket watch; waterproof cases, self-winding and grand complications.
The wristwatch overtook the pocket watch. Military use in the First World War, aviation, water-resistant cases (1926), automatic winding (1923–31), rectangular Art Deco designs and early chronographs and calendars defined the period.

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.
