Seamaster Blue Dial Diver 300 M - Stainless Steel COSC

Omega Seamaster Diver 300 M Ref. 212.30.41.20.03.001 – Pre-Owned 2016 – 41mm – Blue Dial – Automatic Movement – Steel Bracelet

"Elegance is always ready to dive."

Picture yourself standing on a cliffside, watching the sun set over the ocean horizon—or rushing to make a meeting after a morning swim. The Omega Seamaster Diver 300M fuses the boldness of a true diving instrument with the sophistication of an urban timepiece. Rugged, technical, and refined, it perfectly embodies a spirit of everyday adventure.

Since 1948, the Omega Seamaster collection has expressed the brand’s passion for the maritime world. Initially designed as a waterproof dress watch for postwar gentlemen, the Seamaster quickly became a professional-grade diving tool by the 1950s. In 1993, the Seamaster Diver 300M marked a turning point: a wave-pattern dial, helium escape valve, and ceramic bezel gave it both character and technical edge. Worn by James Bond in GoldenEye, it quickly entered the horological hall of fame. The reference 212.30.41.20.03.001, produced from 2012 to 2019, is a direct heir to this legacy—modernized but loyal to its adventurous DNA.

The timepiece presented here dates from 2016 and features the Omega Caliber 2500, a COSC-certified automatic movement with a 48-hour power reserve. Water-resistant to 300 meters, it also includes a helium escape valve engraved with Omega’s signature seahorse emblem. The 41mm stainless steel case is fitted with a unidirectional rotating ceramic bezel in blue. The matching blue wave-pattern dial features applied luminous markers, skeletonized Super-LumiNova hands, and a date window at 3 o’clock. It is protected by a domed sapphire crystal with double-sided anti-reflective coating. The watch is mounted on a brushed and polished steel bracelet with secure folding clasp and diver’s extension.

A watch built for every adventure

From the open sea to the terrace of a marina restaurant, the Seamaster Diver 300M is the perfect companion—resolutely premium, durable, and versatile. It transitions seamlessly from a wetsuit to a business suit, capturing the essence of refined utility.
