A Tribute to the Ocean

On the solid case-back of the Omega Seamaster Diver 300M Summer Blue, a special 75th-anniversary medallion takes center stage. This medallion depicts Poseidon, the Greek god of the ocean, accompanied by a pair of seahorses. This unique case-back design is shared across all eight references of the celebratory collection, symbolizing the brand’s deep connection to the sea.


The dial of the Seamaster Diver 300M Summer Blue remains faithful to the iconic Seamaster Diver 300M style, with a few notable updates. Crafted from ceramic and laser-engraved with a wave-like pattern, the dial now showcases a sunray-brushed gradient Summer Blue varnished finish, exuding a sense of sophistication and depth.

The applied indices and skeleton hands feature a light blue Super-LumiNova insert, ensuring optimal legibility even in low-light conditions. The date window at 6 o’clock displays a blue disc with light blue digits, seamlessly blending with the overall aesthetic of the watch.


Powering the Omega Seamaster Diver 300M Summer Blue is the Omega Co-Axial Master Chronometer Calibre 8800. Sandwiched between the dial and the closed case-back, this movement operates at a frequency of 25,200 vibrations per hour and offers an impressive power reserve of up to 55 hours. This exceptional movement guarantees precision, reliability, and performance.
