Rolex · Family: Sea-Dweller
The Rolex Sea-Dweller 126600 is the house's saturation diver, introduced in 2017 for the model's 50th anniversary: a 43mm Oyster case in Oystersteel, black Cerachrom bezel, helium escape valve, and 1,220 meters of water resistance. It revives the red "Sea-Dweller" line and is the first Sea-Dweller with a Cyclops lens over the date. It runs the Calibre 3235 with 70 hours of reserve. Cazador has no verified price observations for this reference yet (n=0).

The Sea-Dweller was born in 1967 with reference 1665, developed for saturation diving: its Rolex-patented helium escape valve let professional divers from companies like COMEX decompress without the crystal popping off from helium trapped inside the case.
For half a century the model lived in the Submariner's shadow as the extreme tool for professionals: from the "Double Red" 1665 to the 16600 and 116600, always without a Cyclops and with four times its sibling's depth rating.
In 2017, for the 50th anniversary, Rolex introduced the 126600: it grew to 43mm, brought back the red "Sea-Dweller" line as a nod to the original 1665, and added the Cyclops lens over the date for the first time — a small sacrilege for purists that became the generation's signature. The Calibre 3235 with Chronergy escapement raises the reserve to 70 hours.
In Cazador's catalog it completes the Rolex diver trio alongside the Submariner: more case, more depth, and the saturation-diving heritage that defined the category.

A 43mm case versus 41mm, 1,220m water resistance versus 300m, a helium escape valve, and a noticeably thicker case. The Submariner doesn't need one: it isn't built for saturation diving.
Because no Sea-Dweller had carried one in 50 years: the lens required a thinner crystal incompatible with the model's depth ratings. The 126600 was the first to fit it.
It is a tribute to the original 1665 of 1967, known as the "Double Red" for its two lines of red text. The 126600 revives one red line for the 50th anniversary.
In saturation diving, helium seeps into the case; during decompression, the valve releases it automatically, preventing the crystal from being blown off by overpressure.
