Catalogue description
Dealer description — Vintage Watch Specialist
A Very Rare Jumbo (37.5mm) Cased, Tudor Oyster Prince Date+Day, Model Ref: 7017/0 in Superb Condition with Tudor Box, c.1970 During the 1970s, Tudor faced challenges due to the quartz crisis, which led to a decline in mechanical watch sales. However, the brand made a remarkable comeback in 2009 under new leadership. It repositioned itself as an independent entity within the Rolex family while maintaining its commitment to quality craftsmanship. Today, Tudor is celebrated for its distinctive design language inspired by vintage models from its archives. Its timepieces continue to offer exceptional reliability and precision due to their rigorous testing process. What’s On Offer Produced from 1969 onwards, the Oyster Prince Date+Day is one of the largest TUDOR watches in the Prince line. The example of reference 7017/0 on offer here has a 37.5 mm steel case. Its screw-down waterproof case back is inscribed “Montres TUDOR S.A. Geneva Switzerland Patented” on the inside. On the outside, the case back is engraved “Original Oyster Case by Rolex Geneva”. The self-winding movement with date and day mechanisms is A.S. Calibre 1895. The dial is a stunning silver sunburst and features baton hour markers and luminescent dots beside the hour markers on the minute track around the circumference of the dial, luminescent baton hands and a large seconds hand. The date is visible in an aperture at 3 o’clock and the day of the week in a large aperture at 12 o’clock. This watch is in superb condition with barely any signs of noticeable wear, it has clearly been meticulously looked after and it shows! The watch also comes with its very own period-correct Tudor inner & outer box, which is another rarity itself. This JUMBO-sized reference is rather rare to find and especially in such good condition, so we are very pleased to be able to offer this watch for sale.
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.

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.
