Catalogue description
Dealer description — Vintage Watch Specialist
What's on Offer This Relliac Automatic Diver is a striking example of 1970s Swiss sports watch design, combining bold aesthetics with dependable mechanical engineering. Housed in a substantial 37mm stainless steel case, the watch features a black dial with oversized luminous markers, a rotating diver-style bezel and a distinctive red date display that adds a welcome splash of colour. Powered by the highly regarded ETA 2472 automatic movement with 25 jewels, the watch delivers reliable performance and remains one of the most respected Swiss automatic calibres of its era. The movement is protected by a stainless steel case marked as waterproof, antimagnetic and shock-resistant, highlighting the practical tool-watch credentials that were so important during the period. The black dial remains highly legible thanks to its contrasting luminous hands and hour markers, while the large triangular markers at 12 and 6 o'clock reinforce the watch's diving-inspired character. Fitted to a modern black rubber strap, the watch has a purposeful sporting appearance that suits both casual and everyday wear. For collectors seeking an attractive vintage diver that stands apart from the more commonly encountered Swiss brands, this Relliac offers plenty of period charm, reliable mechanics and unmistakable 1970s styling. Overall, the watch is in very good vintage condition and presents well for its age. The stainless steel case retains strong lines with light signs of wear consistent with careful use over the decades. The black dial displays attractively with clear printing and well-preserved luminous markers, while the bezel remains sharp and visually appealing. The plexiglass crystal shows minor signs of age-related wear commensurate with a vintage watch. The ETA 2472 automatic movement is running well at the time of listing.
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.
