Rolex Sea-Dweller

In 1978, the original Sea-Dweller (Reference 1665) was replaced by the Reference 16600. This new model boasted an even greater depth rating: an impressive 4000 feet (or 1220 meters). This was possible, in part, due to a larger Helium Escape Valve. Visually, the 16600 stands apart from its predecessor with a glossy dial featuring applied luminous markers. The internals were also upgraded with the Calibre 3035 movement. Rugged, dependable, and beautiful the Reference 16600 is the last 'Dweller with classic Oyster dimensions. This particular example has a T-serial and dates to circa 1996. It features an outstanding professionally refurbished 'holey' lug case with a helium escape valve, a rich glossy black Tritium dial and matching handset, and a matching Oyster bracelet with solid ends. This is a rugged and beautiful watch from the last era of classically proportioned Rolex sports watches.
