Description

''With Service''
The Rolex Sea-Dweller 16660, often nicknamed the “Triple Six,” represents a significant evolution in Rolex’s line of professional dive watches. Introduced in the early 1980s, it was designed to meet the demanding needs of commercial saturation divers, boasting a remarkable water resistance of up to 1,220 meters (4,000 feet).

This model features a larger and thicker stainless steel case compared to its predecessors, improving durability under extreme pressure. The Sea-Dweller 16660 introduced Rolex’s first helium escape valve (HEV), allowing trapped helium gas to safely exit the watch during decompression, preventing damage to the case.

With a matte black dial, large luminescent hour markers, and a unidirectional rotating bezel with a black insert, the 16660 combines practical legibility with timeless aesthetics. The watch is powered by the Rolex Caliber 3035 automatic movement, known for its precision and reliability, featuring a quickset date function.

Highly respected among dive watch enthusiasts and collectors, the Sea-Dweller 16660 stands as a rugged tool watch icon — built for professional use yet stylish enough for everyday wear.
