Without doubt my favourite Ceramic bezel Sea-Dweller ever produced, and one of just a few examples for sale in the UK. This SD 4000 is complete with its Rolex box, instruction booklet, bezel protector, swing tag and UK-supplied Rolex international warranty card dated Sep 2014. 

Only in production for 3 years (2014-2017), and exclusively in a 40mm steel case, this Sea-Dweller 4000 ref. 116600 with helium escape valve, features the flat scratch-proof sapphire glass (without the date magnifier found on the SD43's) that us purists appreciate. Fitted to its robust Oyster bracelet, with Glidelock extension, waterproof to an impressive 1220m, and powered by Rolex's self-winding calibre 3135.
