Catalogue description

Dealer description — Craft & Tailored

Founded in 1918 in Japan, Citizen is one of the most integrated manufactures in the watch world. They make all of their watch components in-house and do not have any manufacturing facilities outside the brand's home country. With a history of cutting edge technology, Citizen is known for their incredibly accurate and rugged time pieces. The history of Citizen divers from the 1960s-1980s is rather elusive. However, what we do know is that the company was very well know for producing dependable divers in this time period as well as highly regarded pressure-rated quartz divers. This particular military dive watch is in excellent condition for its age, and is a rather striking example of just how strongly such sought-after, yet affordable Citizen military watches can hold up over time.

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.
