This 16600 Sea-Dweller from 1998 has aged beautifully over the last 21 years with the Tritium lume turning a pale cream colour and the original bezel taking on a deep blackberry blue hue. Remarkably complete with its Rolex box, original punched certificate, wallet, booklets, bracelet tool, extension link, chronometre tag, dive tables and calendar card. Savvy collectors have long recognised the comparative scarceness of these models compared to the more widely recognised Sub and all of these 16600's have proved superb investments.
