Omega Seamaster DIVER 300M CO‑AXIAL MASTER CHRONOMETER Ref.210.30.42.20.01.001

THE LEGEND RETURNS — WITH MODERN MASTERY

The Seamaster Diver 300M has been a cornerstone of OMEGA’s legacy since its launch in 1993 — a timepiece born from the brand’s deep connection to the ocean and spirit of exploration. Revered by divers, athletes, and adventurers alike, this contemporary 42 mm version carries that tradition forward with updated materials, masterful engineering, and timeless style.

MARINE HERITAGE, MODERN DESIGN

Crafted in polished and brushed stainless steel, the 42 mm case strikes a perfect balance between sport and sophistication. Framing the watch is a black ceramic bezel, which features a white enamel diving scale — engineered to be both fade-resistant and easily legible, even in the most challenging environments.

The polished black ceramic dial, laser-engraved with the Seamaster’s iconic wave motif, shimmers with depth and texture. The skeletonised hands and raised hour markers, all filled with white Super-LumiNova, ensure optimal readability day or night — glowing a radiant blue under low light.

A discreet date window positioned at 6 o’clock keeps the dial symmetrical and clean, while the helium escape valve at 10 o’clock reminds us of its professional diving DNA.

MASTERFUL PRECISION FROM WITHIN

At its core, this Seamaster Diver 300M is powered by the OMEGA Co-Axial Master Chronometer Calibre 8800 — a movement certified to the highest standards of precision, magnetic resistance, and chronometric performance by METAS.

This automatic movement resists magnetic fields up to 15,000 gauss and offers a power reserve of 55 hours, with a rhythm as smooth as the tides. Turn the watch over, and a transparent sapphire crystal caseback reveals the elegant finishing — from Geneva waves in arabesque to the finely decorated rotor.

READY FOR DEEPER HORIZONS

Built to withstand depths of up to 300 meters (1000 feet), this timepiece is as robust as it is refined. The unidirectional rotating bezel, screw-in crown, and diving extension make it a reliable tool for any aquatic pursuit, while its steel bracelet offers comfort, security, and a seamless fit thanks to the patented adjustable clasp system.

A MODERN CLASSIC FOR THOSE WHO DARE

Whether you’re navigating ocean currents or the fast pace of daily life, the Seamaster Diver 300M 42 mm in black and steel delivers effortless elegance, technical brilliance, and a legacy that lives on every wrist.
