Catalogue description

Dealer description — Craft & Tailored

Antoine LeCoultre created the LeCoultre brand in 1833, which originally created movement blanks or unfinished movements for some of Switzerland's most prestigious watchmaking houses such as Vacheron Constantin, Audemars Piguet, and Patek Philippe. LeCoultre merged with Jaeger in 1937 to form Jaeger-LeCoultre and went on to become the brand we know and love today, though until the 1980s Jaeger-LeCoultre reserved the name “Jaeger” only on their watches destined for the United States. The Jaeger Master Mariner was created in celebration of the Jaeger brand's 125th anniversary and has taken on many shapes and variants over its production period, all featuring an aesthetic that married sophistication and utility in one.

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.
