Ref. 210.30.44.51.03.001

When precision meets the ocean.
The OMEGA Seamaster Diver 300M Chronograph 44 mm is a bold evolution of a true diving legend. Born from OMEGA’s long-standing relationship with the sea, this model blends advanced chronograph functionality with striking marine-inspired aesthetics and Master Chronometer performance — making it a perfect companion for deep-sea adventures or refined everyday wear.

BUILT FOR THE DEPTHS. DESIGNED FOR LIFE.

This 44 mm model is crafted from stainless steel, with a polished blue ceramic bezel featuring a white enamel diving scale — offering exceptional durability and long-lasting clarity. The matching blue ceramic dial, laser-engraved with the iconic wave pattern, reflects the dynamic energy of the ocean while maintaining the collection’s signature visual identity.

At the heart of the dial lie two subdials:

• A 12-hour and 60-minute chronograph counter at 3 o’clock

• A small seconds subdial at 9 o’clock
  All presented with intuitive symmetry and a sleek layout. A date window at 6 o’clock enhances functionality without disrupting balance.

The rhodium-plated hands and raised indexes are coated with white Super-LumiNova, glowing blue in low-light conditions for exceptional legibility under the sea or after sunset.

The chronograph pushers, crafted in polished blue ceramic, offer tactile precision and a cohesive design aesthetic.

A MOVEMENT WORTHY OF THE MISSION

Powering this model is the OMEGA Co-Axial Master Chronometer Calibre 9900 — a powerhouse movement that has passed the industry’s most stringent certification by METAS. It’s resistant to magnetic fields up to 15,000 gauss, delivers superior chronometric performance, and offers a robust 60-hour power reserve.

Equipped with a column wheel and vertical clutch, the movement allows for smooth, reliable chronograph operation with no stutter or jump. Through the transparent sapphire caseback, you can admire the movement’s luxurious finishing — complete with Geneva waves in arabesque and OMEGA’s signature attention to detail.

READY FOR ANY DEPTH

With a water resistance of 300 meters (1000 feet), a helium escape valve, unidirectional rotating bezel, and screw-in crown, this timepiece is fully equipped for professional diving.

The stainless steel bracelet features OMEGA’s extendable foldover clasp with diver’s extension and micro-adjustment — ensuring a secure, tailored fit whether worn bare or over a wetsuit.

DYNAMIC. REFINED. UNCOMPROMISING.

This Seamaster Diver 300M Chronograph represents the perfect balance between tool-watch reliability and modern luxury. Its bold blue-on-steel colorway, technical excellence, and ocean-driven design make it a natural choice for those who demand more from their timepiece.
