The OMEGA Seamaster Diver 300M Nekton Edition 42mm (Ref. 210.30.42.20.01.002) represents OMEGA’s partnership with Nekton, the not-for-profit research foundation committed to ocean protection and management, through a distinctive specification featuring Grade 5 titanium unidirectional bezel with laser-ablated diving scale and black ceramic ZrO2 dial with polished wave relief pattern. The caseback is embossed with the Nekton submarine medallion and oriented precisely using OMEGA’s innovative NAIAD LOCK system that prevents the caseback from rotating out of alignment.

At 42mm with 13.66mm thickness through polished-brushed stainless steel construction, this provides substantial diving watch presence whilst the Grade 5 titanium bezel offers superior strength-to-weight ratio and corrosion resistance beyond standard steel alternatives. The laser-ablated black ceramic dial with matt finish and polished waves in positive relief creates sophisticated depth whilst the stainless steel bracelet with foldover clasp and diver extension provides a dressier presentation than a rubber or fabric alternative.

The Master Chronometer Calibre 8806 delivers 55-hour power reserve with 15,000 gauss magnetic resistance through METAS certification at the industry’s highest standard, with the free-sprung balance and silicon balance spring providing consistent accuracy whilst the rhodium-plated rotor and bridges with Geneva waves in arabesque demonstrate exceptional movement finishing. The screw-in crown and helium escape valve validate professional diving capability throughout.

The domed sapphire crystal with anti-reflective treatment on both sides ensures optimal underwater clarity whilst the 300m water resistance confirms the diving credentials that underpin the Nekton partnership.
