Up for grabs is a lovely example of the transitional Rolex Sea-Dweller, the Reference 16660, nicknamed the “triple 6”. This particular example was produced in 1983. and features the highly-desirable “matte” dial, which was phased out in favor of the gloss dial just a short time after. The 16660 was the first Sea-Dweller to have a sapphire crystal and a larger helium valve that allowed it to descend to the deeper depth of 1220 meters/4000 feet underwater. Rolex also updated the movement, equipping these with the caliber 3035, which replaced the caliber 1575 of the old reference 1665 models.
This Rolex Sea-Dweller is in excellent vintage condition. The case does not show signs of polishing, with the factory beveled edges still visible, and a thick and beefy case, and normal wear. The dial is beautiful, with no flaws, chips, or damage. The original tritium lume is still present in both dial and hands, aged to a creamy yellow color. The watch comes on its original Rolex 93160/592 Oyster bracelet, with 12 full links, diver’s extension, and practically no stretch.
