Omega Seamaster Diver 300M Steel Sedna Gold Blue 210.22.42.20.03.002

A More Refined Take on Omega's Modern Dive Icon

The Seamaster Diver 300M has become one of Omega's defining modern sports watches, but the addition of Sedna Gold gives this reference a noticeably different personality. Rather than changing the formula, Omega elevates it, pairing the collection's proven dive watch architecture with warm Sedna Gold accents that bring a greater sense of refinement without sacrificing the everyday versatility that has made the Seamaster such a favorite among enthusiasts.

This 2020 example combines the striking blue ceramic dial and bezel with Omega's proprietary Sedna Gold bezel, crown, and helium escape valve, creating one of the collection's most elegant modern configurations. Powered by the Master Chronometer Caliber 8800 and accompanied by its original presentation accessories, it offers an exceptional balance of luxury, practicality, and long-term value.

Condition

The watch is running well and presents very well overall. The sapphire crystal is free of notable imperfections, while the case, ceramic bezel, blue rubber strap, and stainless steel buckle all remain in excellent cosmetic condition with no major concerns to note.

The caseback does show cosmetic tool marks from a previous opening, likely the result of routine service or maintenance. These marks are limited to the caseback, do not affect the watch's performance, and are not visible while the watch is being worn. The front flap on the outer white presentation box has detached, while the inner wooden presentation box remains in excellent condition.

Why We Like It

The Seamaster Diver 300M has long been one of the most versatile luxury sports watches on the market, and this Steel and Sedna Gold configuration showcases the collection at its most refined. Omega's proprietary Sedna Gold isn't simply a cosmetic upgrade. Its richer tone complements the blue ceramic dial beautifully while offering improved resistance to fading over time compared to traditional rose gold alloys. The result is a watch that feels noticeably more luxurious while preserving the everyday wearability that defines the Seamaster.

Mechanically, it delivers everything enthusiasts expect from Omega's flagship dive watch. The METAS-certified Master Chronometer Caliber 8800 provides outstanding accuracy, exceptional anti-magnetic resistance, and dependable everyday performance, while the ceramic bezel and 300-meter water resistance ensure the watch remains every bit as capable as its stainless steel counterpart. For buyers who appreciate the Seamaster's proven reputation but want a configuration with a little more warmth and sophistication, this reference offers one of the most compelling combinations in the modern Omega lineup.
