About This Piece

A timepiece with lashings of precision and all the makings of the perfect diver's watch, this OMEGA Seamaster Ploprof 1200M Co-Axial Master Chronometer O-MEGA Steel Watch is nearly impossible to resist. Taking design cues from OMEGA’s iconic 1970s original, the mono-bloc case is crafted in O-MEGASTEEL—a nickel-free alloy celebrated for its hypoallergenic properties and resistance to corrosion. Featuring the signature screwed-in crown and the characteristic security pusher at 2 o’clock, enhanced with a ring in striking blue ceramic, this Summer Blue marvel beckons you to the ocean with its iconic wave pattern on the dial - a nod to its formidable 300m water resistance. And the bezel, produced in transparent sapphire crystal and varnished blue on the back, reveals a delicate light blue diving scale beneath. If this timepiece isn’t an invitation to explore the wonders beneath the waves, nothing is.

Editor's Notes


A legend of oceanic proportions, the OMEGA Seamaster 300 of today is leaps and bounds from the original. Although it may have been born in 1957, the Seamaster 300 has seen a number of enhancements over the years. And today? This clean, crisp and Master certified collection still maintains its vintage charm.

Behind the commemorative caseback, where Poseidon and his two seahorses reign supreme, beats the luxurious OMEGA Co-Axial Master Chronometer calibre 8912, boasting a 60 hour power reserve. And in oceanic harmony, the varnished hands and indexes glow with light blue Super-LumiNova. Complete with an original-style blue rubber strap, this is one watch you’ll turn to time and time again.
