Released in 2017 to mark the anniversary of the worlds most celebrated dive watch, this (first series) Rolex Sea-Dweller ref. 126600 sports the iconic red-writing on the black luminous dial, a respectful nod back to the grail "DRSD" reference "1665". Produced in a 43mm steel case, this sought-after Sea–Dweller is waterproof to an impressive 4000ft and features a unidirectional Cerachrom dive bezel, a scratch resistant sapphire crystal (it's the first S.D. to feature a cyclops) and is fitted to the super comfy Oyster Fliplock bracelet with dive extension. Powered by Rolex's upgraded and improved self-winding calibre 3235 movement, with a generous 70-hour power–reserve. Accompanied totally complete with its Rolex box, instruction manual, booklets, swing tags & UK stamped international Rolex warranty card dated August 2017.
