The OMEGA Seamaster Diver 300M 42 mm is a masterful expression of precision, design, and the brand’s enduring maritime heritage. Its stainless steel case and bracelet provide a robust yet sophisticated framework, while the Summer Blue ceramic dial, treated with PVD and finished with a subtle gradient, evokes the depth and allure of the ocean.

The dial also features the iconic 300M wave pattern, a hallmark of this legendary collection. Encircling the dial is a blue ceramic bezel with a Summer Blue enamel (Grand feu) diving scale, perfectly complementing the dial’s aquatic tones. The display is completed with rhodium-plated skeleton hands and raised indexes, all filled with a distinctive light blue Super-LumiNova for exceptional legibility, day or night.

On the reverse, the watch reveals a stamped commemorative Seamaster logo, depicting Poseidon with his trident flanked by two seahorses, inspired by OMEGA’s 1956 original and reinterpreted for the present day. Beneath, the Co-Axial Master Chronometer Calibre 8800 powers the timepiece, certified to the highest standards by METAS for precision, performance, and magnetic resistance.
