The devil is in the details and this early ‘Triple Six’ Sea-Dweller has plenty to get excited about.
Rest assured, this Sea-Dweller’s ‘Triple Six’ moniker has little to do with Satanism but rather refers to its reference number ‘16660’. Introduced in 1978, the 16660 is an important transitional reference in Rolex’ line-up of dive watches and the archetype for every modern Rolex toolwatch. The ‘Triple Six’ combines the vintage details of its predecessor, the ref. 1665, with some notable technical improvements. It was one of the earliest Rolex models, and the very first Rolex toolwatch, to receive a sturdy sapphire crystal. Together with a thicker case and improved helium escape valve, this gave the 16660 a significantly increased depth rating at 4,000 feet / 1,200 meters, double that of its predecessor.
Early specimens of the 16660, like this one from 1982, still sport the vintage style matte dial with painted tritium hour markers. These dials came in two executions. This watch features the desirable Mk 1 dial variation that has turned a lovely anthracite color together with warm light custardy lume plots.
The watch is in amazing shape for a toolwatch of its age. The case is very thick and sharp and comes with a pretty faded bezel insert and brown discolored lume pip. The watch comes on a correct 93160 but updated with sturdier "solid end links".
