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.
