This pre-owned Omega Seamaster Diver 300M ref. 217.30.42.21.01.001 (2026) is a high-performance dive watch that blends technical precision with a refined modern aesthetic. It features a 42mm polished-brushed stainless steel case paired with a black ceramic bezel, highlighted by a white enamel diving scale and a polished grade 5 titanium inner ring for enhanced durability and contrast. The matte black dial is fitted with rhodium-plated hands and indexes filled with white Super-LumiNova, along with four rhodium-plated Arabic numerals for excellent legibility in all conditions. Powered by the Omega Co-Axial Master Chronometer Calibre 8912, it delivers METAS-certified accuracy, anti-magnetic performance, and robust reliability. Finished on a stainless steel bracelet with an extendable foldover clasp and diver extension, and secured by a titanium screw-in caseback engraved with the iconic seahorse, this Seamaster is a true professional-grade diver built for both function and style.
Pre-owned OMEGA Seamaster Diver 300M ref 217.30.42.21.01.001 (2026) is the latest edition of the brand-new 4th generation Planet Ocean. The collection initially debuted back in 2005 as a more capable version of the Seamaster Diver 300M. The second generation debuted in 2011, followed by the 3rd generation in 2016. Now, as of 2025, ref. 217.30.42.21.01.001 carries forward the newest collection, complete with a cleaner aesthetic (no date or helium escape valve), a new bracelet, and a clean, black-and-silver design set. The 42mm stainless steel case is paired with a black ceramic bezel and white enamel diving scale, giving it a sharp, high-contrast look, while the matte black dial prioritizes legibility with bold, luminescent hour markers and hands. Rhodium-plated hands and markers filled with Super-LumiNova stand out clearly in low light, and the addition of Arabic numerals at the cardinal positions gives it a very dynamic design. The bracelet includes a diver extension, making it practical for everyday wear and beyond. It’s a more contemporary take on the Seamaster, with a focus on clarity, durability, and function.
