A modern classic in Omega’s dive watch collection, the Seamaster Diver 300M, reference 210.30.42.20.01.001, blends high-performance engineering with bold contemporary design. This certified pre-owned model from 2024 is offered in very good condition and delivered as a full set, including original box, warranty card, and all documentation.
The watch features a 42 mm stainless steel case with a mix of brushed and polished surfaces, complemented by a black ceramic bezel with white enamel diving scale. The wave-pattern black ceramic dial adds visual depth and is fitted with luminous skeleton hands and hour markers for optimal legibility in low light.
A date window at 6 o’clock maintains symmetry and functionality, while the helium escape valve at 10 o’clock and screw-down crown reinforce its professional diving credentials.
At its core beats the OMEGA Co-Axial Master Chronometer calibre 8800—a self-winding movement certified by METAS, offering high precision, magnetic resistance up to 15,000 gauss, and a 55-hour power reserve. The movement is visible through the sapphire exhibition caseback, showcasing Omega’s attention to detail.
Fitted with a robust stainless steel bracelet and secure folding clasp with diver extension, this Seamaster is ready for both underwater adventure and everyday elegance.
Fully certified pre-owned, professionally inspected, and authenticated, this 2024 Omega Seamaster Diver 300M is a perfect balance of iconic design, cutting-edge mechanics, and versatile wearability—a top-tier choice in the world of luxury dive watches.
