Omega Seamaster
The Seamaster line was born in 1948 and now brings together Omega's diving and leisure watches. The Seamaster Diver 300M, launched in 1993, has been worn by James Bond on screen since 1995. Many recent versions are certified Master Chronometer by the METAS institute.
Main families
- Seamaster Diver 300M: ceramic bezel and wave-pattern dial on recent versions.
- Seamaster Aqua Terra: a versatile version, without a rotating bezel.
- Seamaster Planet Ocean: diving to 600 m, launched in 2005.
- Seamaster 300: inspired by the 1957 model.
What drives value
- The family and generation (Co-Axial calibre, Master Chronometer certification).
- The diameter and metal.
- Editions linked to James Bond or the Olympic Games.
- The box, the warranty card and the condition of the bezel.
Price benchmarks are published on the Value page: they are market estimates, not sale prices.
Authentication checkpoints
- Serial number matching the warranty card.
- Quality of the bezel and its graduations.
- Finishing of the Co-Axial movement visible through the sapphire caseback.
- Inspection by a watchmaker.
None of these signs is enough on its own to guarantee authenticity: features vary across years and references. Every piece is examined as a whole by our experts before any offer.
How to describe your search
- Give the Seamaster family and diameter you want.
- Specify the dial colour and the strap or bracelet.
- Let us know if a special edition interests you.
Seamaster Omega: every piece we offer is one of a kind, appraised then photographed in our Paris workshops before going online. A collectible watch is judged on the consistency of its overall condition: unpolished case, original dial and serviced movement.
How to authenticate
- Case and movement numbers consistent with each other and with the reference
- Calibre opened in workshop: original finishes, engravings and parts
- Original dial and hands, homogeneous lume, no repainting
- Strap, deployant buckle and links stamped by the manufacturer
