Seamaster 300 Master Co-Axial Titanium / Blue / Bracelet

No-date version of caliber 8500. Self-winding movement with Co-Axial escapement for greater precision, stability and durability. Resistant to magnetic fields greater than 15,000 gauss. Free sprung-balance with silicon balance spring, two barrels mounted in series, automatic winding in both directions to reduce winding time. Bridges and the oscillating weight are decorated with exclusive Geneva waves in arabesque.

The Seamaster 300 was introduced in 1957 as Omega's response to the growing demand for professional dive watches, alongside the Speedmaster and Railmaster in what became known as the 'Professional' trilogy. The original CK2913 featured a broad-arrow handset, rotating bezel, and 200-metre water resistance — specifications that made it the choice of military dive teams and explorers, including the British Royal Navy. The modern Seamaster 300 revives the original's vintage proportions and design cues — the triangle-at-twelve, the broad arrow hands, the domed dial — while incorporating Omega's Master Chronometer movements with magnetic resistance beyond 15,000 gauss.

The Omega Seamaster 300 Master Co-Axial has a design inspired by Omega's first dive watch, while it is technically fully up-to-date and packed with Omega's latest inventions and materials, like an in-house, anti-magnetic Master Co-Axial movement and a ceramic bezel insert. As reference 233.90.41.21.03.001, the Seamaster 300 has a titanium case and matching bracelet. The blue ceramic bezel ring has a Liquidmetal diving scale.
