Omega Seamaster Diver 300M Co‑Axial Master Chronometer 42 mm – Blue Ceramic Dial – Stainless Steel or Blue Rubber Strap

The Omega Seamaster Diver 300M Co‑Axial Master Chronometer 42 mm in blue ceramic is one of the most recognizable and desirable configurations in the Diver 300M lineup. Combining modern ceramic components, professional diving capability, and Omega’s advanced Master Chronometer movement, this model delivers both luxury and performance.

The watch features a polished blue ceramic dial with a laser‑engraved wave pattern, skeletonized hands, applied hour markers, and a red “Seamaster” signature. A date window sits at 6 o’clock for balanced symmetry. The blue ceramic bezel includes a white enamel diving scale for long‑lasting clarity and durability.

The stainless steel case incorporates Omega’s signature conical Helium Escape Valve at 10 o’clock and a screw‑down crown at 3 o’clock. Inside, the Co‑Axial Master Chronometer Calibre 8800 provides exceptional accuracy, magnetic resistance, and reliability.

Two configurations are shown:

1. Stainless Steel Bracelet Version

Ref: 210.30.42.20.03.001 Mounted on the iconic multi‑link stainless steel Seamaster bracelet with a foldover extendable clasp.

2. Blue Rubber Strap Version
