Omega Seamaster Diver 300M 210.30.44.51.03.001

Omega Seamaster Diver 300M Chronograph SS Blue Dial

Introduced in 2019, reference 210.30.44.51.03.001 expands the modern Seamaster Diver 300M into a more technically ambitious chronograph while preserving the line's core identity. Its 44 mm stainless steel case, blue ceramic bezel, and laser-engraved blue ceramic wave dial give the watch the visual signatures collectors expect from the contemporary Diver 300M family. Power comes from Omega Co-Axial Master Chronometer Caliber 9900, a self-winding column-wheel chronograph movement that places this reference among the strongest serially produced sport chronographs in its segment. The caliber is METAS-certified, anti-magnetic, and visible through the sapphire caseback, which adds meaningful mechanical appeal beyond the watch's dive specification. The layout combines elapsed-time functionality with a date at 6 o'clock, resulting in a dial that remains balanced despite the added complication. Ceramic pushers and the robust 300 meter depth rating underline that this is not a cosmetic chronograph, but a serious professional-style Seamaster with legitimate underwater capability. This is not a limited edition and was released as part of Omega's worldwide 2019 Seamaster Diver 300M Chronograph launch, making it a regular-production reference with broad collector recognition rather than niche-market exclusivity. For buyers drawn to the Seamaster's post-1990s legacy but seeking greater wrist presence and a higher-spec movement than the standard three-hand model, this reference occupies a particularly compelling position. It stands as one of the most complete modern Omega dive chronographs, blending contemporary materials, proven chronograph architecture, and the unmistakable design language that has defined the Diver 300M for decades.
