Rolex Sea-Dweller Ref. 16600 2001 w/ Box

The Rolex Sea-Dweller Ref. 16600 is one of the most respected professional dive watches in Rolex’s history, bridging the gap between vintage tool watches and modern engineering. Produced from the late 1980s through to 2008, the 16600 retains the classic proportions of earlier Sea-Dwellers while introducing sapphire crystal, improved water resistance, and the robust Caliber 3135.

This 2001 example (K serial) represents the later production years of the reference, featuring a clean, no-cyclops dial layout and the signature helium escape valve — a defining characteristic of the Sea-Dweller line. With its balanced 40mm case, aluminium bezel insert, and tool-focused aesthetic, the 16600 remains a favourite among collectors seeking a true professional Rolex without modern bulk.
