Omega Seamaster Diver 300M Summer Blue 210.30.42.20.03.003 42 mm Steel Blue Dial Watch for Men

OMEGA's Summer Blue colour appears on the PVD-treated ceramic dial of reference 210.30.42.20.03.003, graded in tone to echo the watch's water resistance and engraved with the 300M wave motif. It is ringed by a blue ceramic bezel whose diving scale is Summer Blue Grand Feu enamel, on a 42 mm stainless steel case 13.49 mm thick.

Rhodium-plated skeleton hands and raised indexes are filled with a distinctive light blue Super-LumiNova. The caseback is stamped with a commemorative Seamaster logo of a trident-bearing Poseidon and two seahorses, joining OMEGA's 1956 original with the current design. The steel bracelet has a foldover clasp with comfort setting and diver extension, and calibre 8800 brings Master Chronometer certification, 15,000-gauss resistance and 55 hours of reserve.
