Seamaster

Introduced: 1948

Purpose / Inspiration: The Seamaster was created to celebrate Omega’s 100th anniversary, built originally as a refined, water-resistant dress watch for post-war professionals. But over time, it evolved into a true dive legend. From James Bond’s wrist to deep-sea tool watch territory, the Seamaster family is now one of Omega’s most technically capable and widely recognized collections.

Designer: Original concept inspired by WWII Omega military watches; modern evolutions shaped by dive functionality and pop culture exposure (especially the Bond franchise)

Case size:

Vintage: 34–36mm (early models)
Modern core models: 38mm, 41mm, 42mm, 43.5mm, 45.5mm
Case size varies widely depending on sub-line (Diver 300M, Planet Ocean, Aqua Terra, Ploprof)

Case options:

Stainless steel
Titanium
Sedna™ gold (Omega’s proprietary rose gold)
Two-tone and full gold
Ceramic and Liquidmetal™ cases in some high-end models
Helium escape valves on pro divers

Powered by:

Early: Manual and automatic mechanical (Cal. 30T2, Cal. 501 series)
Modern:
- Co-Axial Master Chronometer movements
- Caliber 8800/8806/8900 (Aqua Terra, Diver 300M)
- Caliber 9900 (chronographs)
- METAS-certified: anti-magnetic, COSC+ level precision
Quartz movements used in some 1980s–1990s models (including Bond era)

Bezel:

Early models: smooth or fluted bezels
Diver models: unidirectional dive bezels in aluminum, ceramic, or Liquidmetal™
GMT and regatta timers also appear in certain versions

Dial options:

Classic: silver, black, white, champagne
Diver/Aqua Terra: teak-pattern, wave pattern, sunburst finishes
Lume-filled indexes and hands
Skeleton hands on Diver 300M
Seamaster text often in blue or red

Water resistance:

30m (early dress models)
150m (Aqua Terra)
300m (Diver 300M)
600m (Planet Ocean)
1200m (Ploprof)
All feature screw-down crowns and high-integrity cases

Bracelet:

Stainless steel multi-link bracelet
NATO, rubber, and leather strap options
Adjustable clasp on pro models
Seamless integration and quick-change on newer editions

Still in production, with dozens of variations across Diver, Aqua Terra, Planet Ocean, Ploprof, and Heritage lines. Omega’s most versatile and complete collection.

Why it matters: The Seamaster isn’t just a dive watch—it’s a Swiss precision platform, spanning luxury, tool, and sport categories. Whether you’re in a tux or a wetsuit, there’s a Seamaster for the job. It’s Omega’s backbone, and a major part of modern watch history.

James Bond Wears It. Divers Trust It. You’ll Use It.

From Ocean Floors to Red Carpets

Co-Axial Power. METAS Precision. Seamaster DNA.

Not Just One Watch—A Whole Line of Legends
