Catalogue description
Dealer description — Analog/Shift
It is perhaps one of the greatest injustices in horology that women's wristwatches have not historically received the same respect as their larger cased counterparts, resulting in far fewer executions worth collecting. This is truly a shame - but fortunately, Rolex got the memo long before most, and have been producing outstanding ladies watches for over 50 years. And we're talking about the real thing - not those that utilize faux-gold, not-so-precious stones and batteries - Rolex's offerings are mechanical, functional, wearable art. This thinking even extended to sport models under Rolex's sibling brand, Tudor! Like Rolex, Tudor really seems to get their smaller-wristed clientele, offering watches that are simply scaled-down versions of their most popular men’s models. Tudor had its genesis as a subsidiary of Rolex. It's watches were Rolexes in all but name: same Rolex Oyster case, same crowns, and Rolex crystals. The only difference was what beat inside the Oyster cases — Swiss ETA movements rather than movements that Rolex built in-house. Take this particular piece for example, a Sumbariner 'Mini Sub' Reference 9091/0 . It dates to circa 1977 and features a 31mm stainless steel Oyster case with holey lugs , a Rolex signed crown, a rotating dive timing bezel with a beautiful black insert, and a gorgeous black Tritium dial with a matching handset. Powered by a roust and proven ETA automatic winding movement, this piece comes fitted to a correct stainless steel Oyster bracelet with a signed blade clasp. Lovely! This is easily one of the cleanest Mini-Sub's that we have come across - and is the perfect choice for the smaller-wristed individual for whom 39mm is too large, and 28mm is too small.
Historical context
Quartz Revolution (1969 – 1990)
Seiko's Astron begins mass quartz timekeeping; traditional industries contract sharply.
Quartz and digital watches transformed the market after 1969. Swiss employment collapsed, Japanese and Hong Kong production soared, and the Swatch (1983) helped the Swiss industry recover; mechanical watches survived as luxury goods.

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.
