Nicknamed the ‘Seaweed’ for the deep, oceanic green Omega brought to the Seamaster Diver 300M in 2022, this model trades the usual black or blue for a polished green ceramic dial and bezel. Perfect for the collector who wants a diver for daily wear with more personality than the traditional choices, it backs that standout green with serious diving capability.

Presents itself in mint condition with little to no signs of wear. Made of green zirconium-oxide ceramic, the dial shifts like sunlight through shallow water, its laser-engraved waves catching the light as you turn your wrist. A matching green ceramic bezel, capped with a crisp white enamel diving scale, carries the color all the way around the watch. Brushed and highly polished steel give the case real depth, going matte one second and gleaming the next.

Functions include hours, minutes, seconds, date, and dive timing. Screw-down crown at 3 o’clock unscrews to operate: pull to the first click to quickset the date, then fully out to set the time with hacking seconds. Unidirectional bezel rotates counterclockwise to track your dive time, and the conical helium escape valve at 10 o’clock vents trapped helium during decompression from saturation dives. A 55-hour power reserve keeps it running through the weekend off the wrist, while 300 meters of water resistance carries it well beyond recreational dive depth. White Super-LumiNova on the hands, indexes, and bezel dot ensures legibility across all low-light and underwater conditions.

Comes as a full set, double-boxed with warranty card, master chronometer card, pictogram card, and user manual.

Plenty of divers come in green, but few match the ‘Seaweed’ with its polished ceramic dial and laser-engraved waves on a Seamaster icon over three decades old. If a head-turning diver in this colorway sounds like the piece your collection is missing, inquire today before this one swims off.
