Omega Seamaster 300 Heritage

Omega Seamaster 300 Master Co-Axial – Ref. 234.30.41.21.01.001

An icon reborn. The Omega Seamaster 300 Master Co-Axial pays homage to Omega’s legendary dive watches of the 1950s while delivering modern performance, durability, and precision. With its vintage-inspired design and cutting-edge movement, this Seamaster strikes the perfect balance between heritage and innovation.

The 41mm stainless steel case wears beautifully on the wrist, paired with a black ceramic bezel featuring Liquidmetal™ numerals for exceptional durability. The black “sandwich” dial with faux-patina Super-LumiNova enhances legibility and gives the watch its unmistakable retro character. Powering the watch is Omega’s Master Co-Axial Caliber 8400, METAS-certified for accuracy, magnetic resistance up to 15,000 gauss, and long-term reliability.

This is a versatile tool watch that feels equally at home underwater, in the office, or dressed casually—timeless, robust, and unmistakably Omega.
