Seamaster 300

The Omega Seamaster 300 draws its legacy from the original 1957 dive watch, created for professional divers and military use. This modern 41mm iteration pays tribute to that heritage, blending vintage-inspired aesthetics—like the broad arrow hands and sandwich dial—with contemporary materials and finishing. Collectors value the Seamaster 300 for its faithful nods to the past, while appreciating the upgrades that make it a reliable daily wearer and a capable dive companion.

Reference numbers such as 234.30.41.21.01.001 (steel on bracelet, black dial) and 234.32.41.21.03.001 (blue dial, leather strap) distinguish dial colors and strap configurations. The Co-Axial Master Chronometer Calibre 8912 powers these references, offering METAS-certified accuracy and resistance to magnetic fields up to 15,000 gauss—features that set recent Seamaster 300s apart from earlier models and drive up desirability. Price variation typically follows condition, completeness (box and papers), and dial/strap combinations, with limited editions or discontinued colorways commanding premiums.

When shopping for a Seamaster 300, check for the correct domed sapphire crystal, ceramic bezel insert, and the signature open caseback displaying the movement—these are hallmarks of the latest generation. Earlier Seamaster 300 models (pre-2014) use different calibers and lack the Master Chronometer certification, so confirm the reference aligns with your preference for vintage charm or modern technology. The 300m water resistance, comfortable 41mm case, and anti-magnetic movement make this model a compelling choice for both collection and everyday use.
