Bushells Antiques has dated this piece to the Edwardian era.
Switzerland,
Introduced as the successor to the reference 16660, the 16600 represents the final generation of the classic aluminium-bezel Sea-Dweller, produced prior to the later ceramic references.

The watch is housed in a 40 mm stainless steel Oyster case, engineered for extreme underwater performance and rated to a depth of 1,220 meters / 4,000 feet. Unlike the Submariner, the Sea-Dweller is distinguished by its absence of a Cyclops lens, a deliberate design choice to preserve structural integrity under saturation diving conditions. The watch is fitted with a unidirectional rotating bezel with black insert and a black dial featuring luminous hour markers and hands for optimal legibility.

Powering the watch is the robust and highly respected Rolex Calibre 3135 automatic movement, chronometer-certified and widely regarded as one of Rolex’s most reliable calibers. The case incorporates a helium escape valve on the left flank, a defining technical feature developed for professional saturation divers.

The watch is fitted with a stainless steel Oyster bracelet with a fold-over safety clasp, completing the utilitarian yet highly refined design for which the Sea-Dweller is known.
Offered here as a full collector’s set, the watch includes its original presentation boxes and documentation, enhancing both its historical integrity and long-term collectability. The overall condition of the watch and accompanying accessories is consistent with a carefully worn vintage example, showing signs of use appropriate to age.
