Footnotes

  • Since the 1950s, increasing deep sea drilling for oil and gas and popularity of undersea explorations led to a rise in demand and set a higher standard in water resistant watches. In 1967, Rolex developed a prototype of Sea-Dweller, guaranteed 500m water resistance; however, not all of the early models had the helium escape valve. Finally in 1971, an improved Sea-Dweller was launched, waterproof to 2000ft (610m), equipped with a helium valve, and a fliplock bracelet that allowed divers to wear the watch outside of the diving suits. Another distinctive feature of this watch was the absence of the cyclop, as it had a larger sized crystal than its kind.
