Omega Seamaster 300M Blue Deployant 210.30.42.20.03.001

The Omega Seamaster Diver 300M Blue Ref. 210.30.42.20.03.001 is the modern evolution of one of Omega’s most iconic dive watches, combining contemporary engineering with the recognizable design language that has defined the Seamaster since the 1990s. Introduced as part of the 2018 redesign of the Diver 300M collection, this model features a 42 mm stainless steel case, a blue ceramic dial with laser-engraved wave pattern, and a matching blue ceramic unidirectional bezel with a white enamel diving scale. The dial includes luminous skeleton hands, applied hour markers, and a date window at 6 o’clock, all protected by a domed sapphire crystal with anti-reflective coating. A helium escape valve at 10 o’clock reinforces its professional diving capability while maintaining the distinctive Seamaster look.
