Introduced in 1948, the Seamaster has developed into one of OMEGA’s broadest collections. It includes professional dive watches, versatile everyday models and heritage-inspired designs, with considerable variation in size, movement, water resistance and overall character.
Buying pre-owned provides access to current references alongside discontinued dial colours, previous-generation movements and limited editions. It can also offer a substantial saving against the original retail price, depending on the particular model and its condition.
The Diver 300M is the most recognisable modern Seamaster, combining a rotating dive bezel, strong water resistance and a distinctive technical design. Planet Ocean models take a more substantial approach, with increased water resistance and cases designed around professional diving specifications.
The Aqua Terra offers a cleaner and more understated alternative. It retains useful water resistance and automatic movement construction without the prominent dive bezel found on the professional models. Worldtimer references add a more complex display and a larger case.
The Seamaster 300 draws more heavily on OMEGA’s historic dive-watch designs, while Railmaster, Ploprof, Ultra Deep and other specialist references provide further choices across the wider family.
Case diameter should not be considered in isolation. Thickness, lug-to-lug length, bracelet design and overall weight can make two similarly sized Seamasters wear very differently.
Every Seamaster is inspected before being offered for sale. We check the operation of the movement, crown, winding and setting functions. Where applicable, we also assess the rotating bezel, helium escape valve, crown threads and clasp operation.
The crystal, bezel insert, dial, hands, case, lugs, bracelet or strap and clasp are examined for condition and wear. Any accompanying box, papers, accessories and remaining manufacturer warranty are confirmed within the individual listing.
Our photographs show the actual watch being offered for sale, allowing its condition and included accessories to be examined before purchase.

Yes. Every Seamaster available to purchase is physically held in stock by MVS Watches. We do not advertise watches on consignment or pre-sell watches held by an unrelated third party.
No. The Seamaster family includes professional dive watches such as the Diver 300M and Planet Ocean, but it also includes everyday models such as the Aqua Terra and heritage-inspired collections with different specifications. The water-resistance rating of the individual reference should always be checked.
