The Omega Seamaster Diver 300M, reference 210.20.42.20.01.001, is a modern interpretation of one of the brand’s most iconic professional dive watches. Combining robust construction with refined two-tone aesthetics, this certified pre-owned luxury watch is presented in new condition and supplied as a full set with its original box and papers.
The 42 mm case is crafted in stainless steel and 18K Sedna™ gold, Omega’s proprietary rose gold alloy known for its rich colour and long-lasting brilliance. The matching steel and Sedna™ gold bracelet ensures visual continuity and a balanced wrist presence. The black ceramic dial features a laser-engraved wave pattern, delivering depth and character while remaining highly legible. Applied hour markers and skeletonised hands filled with Super-LumiNova ensure excellent visibility, and a date window at 6 o’clock preserves dial symmetry.
The unidirectional rotating bezel is fitted with a black ceramic insert and a Ceragold™ diving scale, reinforcing the watch’s professional capabilities. Water-resistant to 300 metres, the Seamaster Diver 300M remains true to its tool-watch heritage.
Powering the watch is the Omega Co-Axial Master Chronometer Calibre 8800. METAS-certified, this in-house automatic movement offers exceptional precision, resistance to magnetic fields up to 15,000 gauss, and a power reserve of approximately 55 hours. The movement can be admired through the sapphire crystal case back.
Offered in new condition and accompanied by its original box and papers, this pre-owned luxury watch represents an outstanding opportunity to acquire a full set Omega Seamaster Diver 300M in steel and Sedna™ gold, combining professional diving performance, refined materials, and advanced Master Chronometer technology.
