Cast your eyes on this particularly attractive Rolex Sea-Dweller “Triple Six” Pallettoni, reference 16660, dating to 1982 with a 7.3 million serial number. This 40mm stainless steel example remains unpolished, retaining a notably thick and sharp case with strong original proportions and an exceptionally crisp coronet on the clasp.
The standout feature is its beautifully aged tritium. The matte black Mk I “Pallettoni” dial has developed a rich, deep custard-colored patina across the hour markers, with the handset aging to the same tone. The remarkably even coloration between the dial and hands creates a cohesive, period-correct appearance that collectors of vintage Rolex particularly appreciate. The 16660 represents an important chapter in the evolution of the Sea-Dweller, bridging the earlier four-digit references and the later 16600 while retaining the rugged tool-watch character for which the model is known. This example captures that era exceptionally well, with an honest, well-preserved appearance and plenty of original character.
The bezel and insert remain in good condition, showing minor visible scratches consistent with careful use. The watch is fitted with its original Rolex 93160 Oyster bracelet, stamped G (1982 date code), with all 13 links and dive extension. The bracelet shows only very light stretch. The caseback bears an inscription with the initials of a previous owner, adding a small piece of provenance and history to the watch. The Rolex self-winding movement is running very well, with the date advancing correctly. Superficial signs of careful ownership are present throughout the helium escape valve case and bracelet, while the overall condition remains very nice.
With its unpolished case, thick proportions, crisp chamfers, and beautifully matched tritium patina, this is a highly appealing example of the increasingly collectible matte Mk I Pallettoni Triple Six Sea-Dweller.
