$ 19,650

In the early 1960s deep-sea diving, particularly mixed gas diving, was advancing at a rapid rate. The Rolex Submariner was the quintessential diver at the time, born out of the late 1950s, which set the design standard for most all dive watches that came after. The Rolex Sea-Dweller was first introduced in 1967, through the collaboration with COMEX, a French deep-sea diving company. Comex is sometimes referred to as the NASA of the deep seas and was the foremost pioneer in mixed gas saturation diving.

In typical Rolex fashion, meaning form following function. Most of the Sea-Dweller design was born out of the need to comply with the commercial ISO 6425 diving standard, which defines test standards and features for watches suitable for diving with underwater breathing apparatus in depths of 100 m (330 ft) or more. Rolex developed a rather simple and practical mechanism to solve this issue by developing a helium escape valve on the side of the case that allowed the helium particles to escape while still maintaining an ISO 6425 diving standard and water resistance rating.
