The Omega Seamaster Diver 300M reference 210.20.42.20.01.001 is a brand-new 42mm professional dive watch that pairs a stainless steel and Sedna Gold case with a striking black luminous dial and a scratch-resistant ceramic bezel. This configuration brings Omega's most iconic aquatic lineage together with the warm prestige of Sedna Gold, the proprietary rose-gold alloy engineered to resist fading over decades of wear.

What sets this reference apart is the seamless contrast between the deep black ceramic bezel, the luminous black dial, and the two-tone steel and Sedna Gold bracelet — a combination that reads as equally at home on the wrist underwater as it does at a formal dinner.

Source your dream watch

The Omega Seamaster Diver 300M is one of the most storied tool watches in horological history, tracing its roots to 1993 when Omega set out to create a professional-grade dive watch that matched the technical rigor of a true instrument with the refined finish expected of a Swiss luxury maison. Since its debut the Diver 300M has become a cultural touchstone — worn by fictional secret agents and real-world explorers alike — and each generation has refined the formula without abandoning its purpose. Reference 210.20.42.20.01.001 represents the current co-axial era of this lineage, shaped by Omega's broader push toward in-house movement mastery and next-generation materials that define the collection today.

The 42mm case of reference 210.20.42.20.01.001 is crafted from a combination of polished and brushed stainless steel and Sedna Gold, Omega's proprietary 18-karat rose-gold alloy formulated with copper and palladium to deliver exceptional color stability over time. Unlike conventional rose gold, Sedna Gold is engineered to maintain its warm hue for decades, making it a genuine long-term investment in both appearance and material integrity. The result is a case and bracelet that carry a distinct two-tone character, blending the cool confidence of steel with the warm prestige of gold without feeling ostentatious.

At the heart of the dial design is the black luminous surface — a hallmark of the Diver 300M family — which delivers excellent legibility whether you are scanning a depth reading at the surface or glancing at your wrist across a candlelit table. The unidirectional rotating ceramic bezel provides both the anti-scratch durability that demanding use requires and the rich, deep color contrast that elevates the watch's visual hierarchy. Applied hour markers and hands treated with luminescent material ensure the dial remains instantly readable in low-light and underwater environments, honoring the true purpose of a professional dive watch.

The bracelet continues the steel and Sedna Gold theme of the case, integrating seamlessly with the lugs for a unified, sculpted wrist presence. Omega's attention to finishing — alternating polished and brushed link surfaces — gives the bracelet a dynamic, three-dimensional quality that distinguishes it from simpler two-tone executions. At 42mm the case occupies a commanding yet versatile footprint on the wrist, large enough to project authority without overwhelming a range of wrist sizes, and the lug-to-lug geometry ensures comfortable all-day wear for both active and dressy occasions.

Buying reference 210.20.42.20.01.001 from Bizak and Co. means acquiring a brand-new example through a trusted luxury watch dealer committed to authenticity, competitive pricing, and an exceptional customer experience.
