The helium escape valve thus allows the gas to be released without compromising the watch’s waterproofness. A guarantee of trust for underwater explorers, the Deepsea Challenge is also a source of daily inspiration for everyday wearers on their quest to defy the limits.Rolex Milgauss. Key Features. Size: 40mm. Materials: Oystersteel (904L stainless steel) Features: Time + running seconds; magnetic resistance. Bezel: Fixed; smooth stainless steel. Crystal: Green sapphire.

The Rolex Sea-Dweller “Great White” reference 1665, introduced in 1977, represents a significant evolution in Rolex’s line of professional dive watches.Fitted with the helium escape valve and the Ringlock system, it can withstand the extreme pressure of deep water, to a depth of 3,900 metres (12,800 feet), pushing back the limits of underwater exploration. With the Oyster Perpetual Deepsea Challenge, whose waterproofness is guaranteed to 11,000 metres (36,090 feet), the deepest depths open new horizons. The ultra-high-pressure tank developed in partnership with Comex to test the waterproofness of the Oyster Perpetual Deepsea Challenge.
Helium gas escape valves can come in different shapes and forms but regardless of the specific style, location on the watch, or manufacturer that is producing them, the core purpose of a helium release valve is the exact same: to permit trapped helium gas molecules safely exit the watch case in a safe and controlled manner. To address this issue, Rolex invented and patented the gas escape valve for the Sea-Dweller in 1967. This one-way valve safely allows the helium trapped in the watch to be released at a given.
The Rolex ref. 16660 “Triple Six” was the first Sea-Dweller with a sapphire crystal protecting the dial, replacing the domed Plexiglas crystal found on the older ref. 1665. Of course, sapphire crystal is now standard across all Rolex watches and is especially prized for its scratch resistance.
