Rolex, who developed the first waterproof watch in history, the Oyster diving watch, constantly explores the limits of waterproof technology, and provides safe, reliable and accurate timekeeping support for the new generation of sea explorers. In response to the technological development of saturation diving, Rolex launched the first Sea-Dweller diving watch in 1967, the first helium escape device, with strong waterproof performance and classic style full of sports style, from then on dominate the deep sea, no one else.
The birth of Sea-Dweller
Rolex, which is actively participating in various deep diving expeditions and researches, has accumulated unprecedented technological breakthroughs. In 1967, it launched the first Sea-Dweller diving watch, which has a water resistance of 610 meters (2000 feet) far higher than the standard at the time, and the first Patented automatic helium discharge device. When early saturated divers breathed a mixed gas containing a lot of helium in a hyperbaric chamber to decompress, helium with extremely small molecules would slowly penetrate into the watch case through the rubber ring.
In the subsequent decompression process, because the gas in the watch case is released in the watch at a slower rate than the decompression in the cabin, the air pressure trapped inside the watch is relatively large, so that the mirror surface flies off like a champagne cork. . Therefore, the helium exhaust device can be described as a vital function of deep-sea diving timepieces.
The powerful waterproof performance of the Rolex Sea-Dweller has won the trust of the French diving research company Comex and has become a designated timepiece for employees. For decades, it has witnessed many important diving milestones, including the 534m deep diving record set by the Hydra VIII mission in 1988. , And the 701-meter record of almost reaching the limit of human physiology in a hyperbaric chamber test in 1992.
Waterproof watch movement upgrade
Continuously improving performance In 1978, the water resistance of the new generation of Sea-Dweller was greatly increased to 1,220 meters, becoming the first mass-produced diving watch that broke the kilometer. Ref. 116600, unveiled in 2014, is the first Sea-Dweller after the millennium. It contains the COSC-certified 3135 self-winding calibre, and it re-emerges with a fully improved performance.
In 2017, the brand new Ref. 126600 was released to celebrate the 50th anniversary of the birth of Sea-Dweller. It is equipped with a 3235 automatic winding movement certified by the Rolex Chronometer. In addition to Parachrom hairspring and Paraflex cushioning device, it also adds a patented Chronergy escapement system. Increase the power reserve from 48 hours to 70 hours, and the accurate timekeeping within 2 seconds per day will dominate the ocean!
Keep up with the times
Ref. 126600 with a unique black surface, extra-large luminous hour markers and Benz hands, as well as the red Sea-Dweller inherited from the original appearance in 1967, pays tribute to the glorious history it created. The hour markers, the inverted triangle on the bezel and the hands are coated with patented Chromalight luminous material. Its unique blue light can continue to shine for up to 8 hours, which is twice as long as ordinary luminous materials, ensuring that the wearer can When reading clearly in a dark environment.
The diameter of the watch is increased to 43 mm, and the date window convex lens is added for the first time, so that the wearer can read the date more clearly, taking into account the practicality of daily wear. The Oyster strap is also equipped with a patented Glidelock extension system, which can extend by 2 mm per grid (up to 20 mm in length), which is convenient for divers who wear it to adjust through a heavy wetsuit.
The newly released Sea-Dweller yellow gold Ref.126603 case and bracelet are made of yellow gold steel (combination of Oystersteel and 18ct gold), and the unidirectional rotating 60-minute scale outer ring is equipped with a patent developed by Rolex. The black Cerachrom ceramic bezel is coated with a layer of gold film on the scale using PVD coating technology. The Sea-Dweller on the dial is also presented in golden yellow for the first time, echoing the new color scheme, which is a bit more expensive.
