Catalogue description

Dealer description — Bulang & Sons

The 844 was the very first dive watch to come from Heuer. The brand was highly regarded for its sports chronographs at the time and so decided to outsource the production of its dive watches to French company Georges Monnin. What is rare is to find one of these in awesome condition like the example we have today. Its one of the first series and it’s a cracker! The 42mm steel is really very cool, with huge crown guards and a super nice big bevel on sides. The Mk1 dial is flawless, as are the correct Mk1 cathedral hands (Mk2 dials were different and had Mercedes hands fitted). The watch has a military look due to the red 24-hour Arabic numerals on the inner side of the hour plots. We believe the insert may be slightly later. All told though, this truly is a stunning condition watch ! This early Heuer will come on the pictured Bulang and Sons leather strap and has been fully serviced by our watchmaker. This is a rare watch to find in such flawless condition. Don’t miss out, get in touch today!

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.
