Omega Summer Blue Seamaster Diver , 210.30.42.20.03.003

We are proud to present this exceptional Omega Seamaster Diver 300M Summer Blue, reference 210.30.42.20.03.003, in mint condition.

This special edition Seamaster Diver 300M forms part of Omega’s Summer Blue collection. At its heart is the Omega Co-Axial Master Chronometer Calibre 8800, an automatic movement certified by METAS for exceptional precision, performance and resistance to magnetic fields up to 15,000 gauss. The movement features a Co-Axial escapement and a power reserve of approximately 55 hours, and is visible through the sapphire exhibition caseback.

Reference 210.30.42.20.03.003 is distinguished by its striking Summer Blue gradient ceramic dial, featuring the collection’s unique colour scheme inspired by the ocean depths. The laser-engraved wave pattern, skeletonised hands and applied indexes are enhanced with Super-LumiNova, while a date aperture at 6 o’clock maintains the balanced and highly legible display.

The stainless steel case measures 42mm and is paired with the iconic Seamaster stainless steel bracelet. A blue ceramic unidirectional bezel with Summer Blue diving scale further reinforces the model’s professional diving credentials. Sapphire crystals protect both the dial and exhibition caseback, while the robust construction ensures water resistance to 300m/1,000ft.

Originally purchased in November 2024 and presented in mint condition. Supplied with its original Omega presentation box, outer box and storage box, together with the operating instructions, leather card holder, pictogram card, Master Chronometer card, International Warranty card and original Omega sales receipt. The watch has its original Omega’s manufacturer warranty, valid until November 2029.
