Omega Seamaster Diver 300M 42mm Steel Blue Dial 210.30.42.20.03.001 Omega Seamaster Diver 300M 42mm Steel Blue…

The Omega Seamaster Diver 300M is one of the most storied sport watches ever made, tracing its roots to 1993 and earning global recognition as James Bond's watch of choice across multiple films. Today's generation, represented by reference 210.30.42.20.03.001, refines that legacy with modern materials, superior movement technology, and a design language that balances tool-watch utility with genuine luxury. This pre-owned reference pairs its blue dial with a stainless steel bracelet.

At 42mm in diameter, the stainless steel case of the Seamaster Diver 300M wears with authority on a wide range of wrist sizes without crossing into oversized territory. The case architecture is unmistakably Omega—helium escape valve on the flank, brushed surfaces contrasting with polished edges, and a profile that sits closer to the wrist than its diameter might suggest. Every detail has been engineered to perform in demanding aquatic environments while looking equally at home in urban settings.

The blue luminous dial is one of the defining visual signatures of this reference. The iconic horizontal wave pattern is rendered in deep blue, with applied hour markers and hands coated in Super-LumiNova for strong legibility in low-light conditions. The ceramic unidirectional rotating bezel, engraved and filled with luminous material at the 12 o'clock pip, adds both functional dive timing capability and a premium aesthetic that resists fading and scratching far better than traditional anodized aluminum inserts.

Powering the 210.30.42.20.03.001 is Omega's Co-Axial Master Chronometer movement, the brand's top-tier certification category achieved in partnership with METAS, the Swiss Federal Institute of Metrology. Master Chronometer-certified calibers must demonstrate chronometric precision across eight separate tests and exhibit resistance to magnetic fields of at least 15,000 gauss—a benchmark that dramatically exceeds the requirements of standard COSC chronometer certification. The Co-Axial escapement is a defining feature of this automatic movement.

The stainless steel bracelet matches the case and has a folding clasp with comfort adjustment and a diver extension.
