Omega Seamaster Diver 300M "Seaweed" — 42mm — Ref. 210.30.42.20.10.001

Nicknamed the "Seaweed" for its mesmerizing forest-green dial, this Seamaster Diver 300M is one of the most striking releases in Omega's modern dive lineup. The 42mm stainless steel case houses a laser-engraved wave-pattern dial that shifts from deep green to near-black depending on the light, paired with a matching green ceramic bezel and white enamel diving scale. Rhodium-plated skeleton hands and applied indexes are filled with Super-LumiNova for legibility in any condition, while the signature conical helium escape valve and date window at 6 o'clock round out the details. It's a tool watch with genuine presence — equally at home at depth or under a cuff.

Beneath the wave-edged sapphire caseback beats the Omega Co-Axial Master Chronometer Calibre 8800, certified to the highest standards for precision and antimagnetic resistance, delivering a 55-hour power reserve. Water resistant to 300 meters and fitted on its brushed-and-polished stainless steel bracelet with integrated diver extension and folding clasp, this is a Seamaster that balances serious capability with unmistakable style. Offered here as a full set — box and papers included — fully vetted and authenticated, ready for its next owner.
