Catalogue description

Dealer description — Huntington Company

Timeless and Attainable Start your vintage journey with confidence. History & Significance The ref. 2975-1 represents an early chapter in the Seamaster line as Omega moved into the period of fully automatic, chronometer-grade movements. Produced in the late 1950s, this reference houses the cal. 500, the first iteration of Omega’s famous 500-series automatics that would eventually define the brand’s reputation for reliability throughout the 60s. The design is distinctly mid-century: a clean silver dial, applied indices, dauphine hands, and a classic polished steel case sized for everyday use of the era. This example also features an original Omega bracelet and comes with a period-correct red Omega box, adding notable completeness. Examples in this condition, with both the bracelet and box, do not surface often. Writer’s Thoughts This Seamaster captures the quiet refinement of late-50s Omega. The proportions feel natural on the wrist, the dial carries that soft vintage warmth, and the early cal. 500 gives the watch historical weight. It is one of those references that grows more enjoyable the longer it’s on the wrist. Our Promise Every watch is thoroughly vetted, carefully described with complete transparency, and guaranteed authentic. This Omega is offered in original condition, representing an uncommon and stylish take on one of Omega’s most iconic model families.

Modern Mechanical Horology (1945 – 1969)

Tool watches for divers, pilots and astronauts; electric watches anticipate the electronic age.

The classic era of the mechanical wristwatch: dive watches, chronographs for motor racing and space flight, GMT watches for jet travel, slim dress watches, automatic calendars, and the rise of Japanese manufacturers alongside Swiss, American, German and Soviet industries.

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.
