Released in 2020, this Seamaster Diver 300M reference belongs to Omega’s modern professional diving series and reflects the brand’s continued refinement of ISO aligned underwater watch specifications. The model was developed in partnership with the Nekton Foundation, an ocean research organisation focused on deep sea exploration and marine ecosystem documentation. This collaboration is reflected in specific caseback engraving and dial execution details unique to this reference.
The watch is constructed around a 42mm stainless steel case engineered for pressure resistance and long term structural stability in underwater environments. The bezel insert is manufactured in Grade 5 titanium, selected for its high strength to weight ratio, corrosion resistance, and reduced rotational mass compared to steel components.
The dial is produced using a laser ablated wave pattern applied to a black ceramic surface, creating micro textured relief across the dial plane. This surface treatment is non reflective, reducing light scatter and improving contrast stability between the luminous hour markers, skeletonised hands, and dial background under variable lighting conditions.
Time indication is delivered via a central three hand layout with applied indices filled with luminescent material for low light visibility, consistent with professional dive instrument standards.
Powering the watch is the Omega Master Chronometer Calibre 8806, certified to METAS standards. The movement is tested for magnetic resistance up to 15,000 gauss and regulated for chronometric precision across multiple positions and temperature variations. It features automatic winding with a coaxial escapement architecture designed to reduce friction and extend service intervals.
The screw down caseback features an engraved Nekton Foundation submarine emblem, executed via precision laser engraving, marking the collaboration between Omega and the marine research organisation.
Water resistance is rated to 300 metres, achieved through reinforced gasket sealing, screw down crown architecture, and pressure tested case construction.
This reference is part of Omega’s Seamaster Diver 300M platform, a collection built around ISO 6425 aligned dive watch engineering principles. The design incorporates functional underwater requirements including legibility at depth, rotational bezel timing capability, and pressure resistant case architecture.
The Nekton Foundation collaboration introduces applied branding elements while maintaining full adherence to operational dive watch specifications. The watch integrates these external design references without altering its core functional architecture as a certified diving instrument.
The dial construction, bezel operation system, and helium escape valve configuration are all engineered as functional components intended for saturation diving conditions and professional underwater use cases, rather than decorative application.
This model sits within Omega’s contemporary professional dive watch category, combining ISO aligned underwater functionality with METAS certified movement performance.
The watch integrates anti magnetic silicon based escapement architecture within Calibre 8806, providing resistance to magnetic fields commonly encountered in modern electronic environments. Its ceramic dial and bezel system improves scratch resistance and long term surface stability under repeated exposure to saltwater and pressure variation.
The 300 metre water resistance rating, helium escape valve system, and screw down crown assembly confirm its suitability for professional diving environments, including saturation diving protocols where pressure equalisation systems are required.
Overall, this reference represents a technically specified diving instrument designed for operational reliability under marine conditions, incorporating modern material science and certified chronometric performance standards within Omega’s current Seamaster engineering framework.
For enthusiasts who want a sports watch with technical substance, without all the extra complicated stuff, the Nekton edition becomes a distinctive option inside the Omega Seamaster family.
