UK retailed by Watches of Switzerland in December 1998 and presented with its Rolex box, booklets, 98/99 calendar card, Rolex service history and perforated Rolex warranty papers.

Famous for its flat sapphire glass, this 40mm stainless steel Sea-Dweller ref. 16600 is from the final generation of aluminium bezel sports watches. Interestingly, it's also the first time Rolex used bright green glowing LumiNova luminous for better legibility in low light, especially under water. Though the case is slightly deeper than the Submariner owing to its helium escape valve, it wears comfortably on the wrist due to its compact proportions.

Waterproof to an impressive 4000ft (1220m), fitted to its solid end link 93160A Oyster bracelet with dive extension, and powered by Rolex's self-winding calibre 3135, with 2-day power reserve. Guaranteed for two years.
