Omega Seamaster Professional 300M Chronometer Ref. 2255.80.00 – A Flash of Electric Blue Brilliance

Among Omega's lineup of celebrated divers, the Seamaster Professional 300M Ref. 2255.80.00 stands out as one of the most visually striking. Dubbed the “Electric Blue” Seamaster by collectors, this early 2000s reference reinvents the classic wave dial with a radiant, high-voltage metallic blue—shimmering and dynamic depending on the light. Rare and no longer in production, this model blends serious diving capability with daring visual flair, making it a cult favorite among Seamaster enthusiasts.

The 41mm stainless steel case features a fully polished scalloped bezel—unlike the later ceramic insert variants—which reflects light beautifully and adds to the watch's overall brilliance. Its unidirectional timing bezel offers tactile precision, and together with the screw-down crown and helium escape valve, the watch maintains its 300-meter water resistance with confidence. The bracelet is Omega's classic five-link design: secure, comfortable, and iconic in its own right.

At the heart of this Seamaster is the Omega Caliber 1120, a chronometer-certified automatic movement based on the trusted ETA 2892-A2. It beats at 28,800 vph, offers a 44-hour power reserve, and is protected behind a solid caseback engraved with the Omega hippocampus—an emblem of seafaring excellence. The date complication at 3 o'clock is cleanly integrated, and the dial layout is balanced by bold skeletonized sword hands filled with luminous material for exceptional legibility underwater or at night.

But the true star is the dial itself: a metallic blue wave pattern that shifts from cobalt to ice-blue to navy depending on the angle. Paired with thick applied indices and high-contrast lume, it creates an unmatched wrist presence—especially when paired with the mirror-like finish of the polished bezel. This model is one of the few Seamaster references to blend both luxury sheen and tool-watch grit in such a harmonious package.

For collectors or enthusiasts looking for a distinctive Omega diver with vintage charm and standout aesthetics, the Seamaster 2255.80.00 is a rare and electrifying find—one that remains as powerful on the wrist as it is in Omega's diving legacy.
