The emergence and subsequent progression of scuba diving in industry during the 60s and 70s called for very specially designed equipment. Watches in particular played a significant role in the undertakings of professional divers and were thus tools and relied upon heavily. This new demand for precision timepieces that could tolerate the stresses of prolonged deep water submersion sparked a period of significant innovation within the major Swiss manufactures, keen to capitalise on a fresh and growing market.

Introduced in 1967, The Rolex Sea-Dweller was manufactured as an evolution of the Submariner reference 5513. The 5513, perhaps one of the most famous diving watches in Rolex’s repertoire, was unable to withstand excessive depths for long periods of time. As divers plunged ever deeper the then current technology was tested to its limits and new technologies had to be developed.

This example is extremely collectible and is in fabulous condition with razor-sharp edges and beautiful proportions. It appears that the watch was never worn by a diver and it is thus a rare opportunity for any collector to come across a piece like this, especially when complete with its original accessories.
