The Omega Seamaster Diver 300M “Summer Blue” reference 210.30.42.20.03.003 is a vibrant and contemporary interpretation of the iconic Diver 300M, released as part of Omega’s Summer Blue collection. This certified pre-owned luxury watch features a 42 mm stainless steel case with a matching steel bracelet, offering a perfect balance between sporty performance and refined aesthetics.
The standout feature is its striking blue ceramic dial, enhanced by a gradient finish that transitions from light to deeper shades of blue, symbolising the watch’s connection to the ocean. The dial is decorated with the signature laser-engraved wave pattern and features skeletonised hands and applied hour markers filled with light blue Super-LumiNova for excellent legibility. A date display at 6 o’clock ensures symmetry and practicality.
The blue ceramic bezel is complemented by a diving scale in a contrasting light blue tone, reinforcing its bold and modern identity. Powered by the automatic Omega Co-Axial Master Chronometer calibre 8800, this in-house movement is METAS-certified, ensuring exceptional precision, anti-magnetic resistance, and long-term performance. It offers a power reserve of approximately 55 hours.
Water-resistant to 300 metres (30 bar), this model is designed for professional diving while remaining perfectly suited for everyday wear. Offered in new condition and presented as a full set with its original box and papers, this piece is highly desirable for collectors seeking a modern pre-owned luxury watch.
The Seamaster Diver 300M “Summer Blue” stands out for its distinctive colour palette, advanced movement, and iconic design.
