Additional Informations: This is a unique opportunity to acquire an exceptionally rare and early Rolex Sea-Dweller Ref. 16660 MK1. What makes this transitional version so special is its matte dial—an iconic feature previously reserved for the predecessor reference 1665.
The absolute highlight of this watch is the ultra-rare "single Rolex coronet" case back with a single embossed Rolex crown - a detail found exclusively in the 6-million serial range.
Another collector’s gem is the original Rolex anchor with a green dot, a nearly impossible-to-find accessory that, when available, commands astronomical prices.
Condition? Flawless! The case has been professionally restored to the highest standards, bringing it back to its original factory finish. The Tritium dial and hands have developed an absolutely stunning patina, perfectly complementing the rare faded “Flat Four” ghost bezel insert.
The original Rolex tool-set pouch and certificate have suffered some moisture exposure, but all details remain fully legible and verifiable.
This MK1 Sea-Dweller is a true rarity and a must-have for any serious vintage collector. Don’t miss the chance to own this exceptional piece before it’s gone!
