The Omega Seamaster Diver 300M “Summer Blue” is a striking tribute to Omega’s 75th anniversary—a modern icon infused with nautical spirit and vibrant character. Its radiant blue ceramic dial features a gradient sunburst finish with laser-engraved waves, capturing the essence of deepening ocean tones. Paired with a matching ceramic bezel featuring a Grand Feu enamel diving scale, the watch balances technical sophistication with visual brilliance. The PVD-treated hands and indexes glow with light-blue Super-LumiNova for optimal legibility in any light.

This example is in excellent condition, carefully checked by our in-house Omega-certified watchmaker, and comes as a complete full set. Included are the original special edition outer box, presentation box, travel box, card holder, international warranty book, and Omega warranty card dated 10.02.2024, with active Omega factory warranty valid until February 2029.

The 42 mm stainless steel case houses Omega’s Co-Axial Master Chronometer Calibre 8800, METAS-certified and offering magnetic resistance up to 15,000 gauss. Water-resistant to 300 meters, it features a helium escape valve and screw-down crown—making it not just a showpiece, but a serious dive instrument.

Fitted on the original steel bracelet with all full links, it is suitable for a wrist size up to 20 cm, with a diving extension up to 22 cm.

A celebration of design and innovation, the “Summer Blue” is a standout choice for anyone seeking one of the most collectible modern Seamasters.
