This weekend we had another first-time winner on the PGA Tour. J.T. Poston went out on Sunday, fired a bogey-free 62, and then hoisted the Wyndham Championship trophy up in the air while wearing what looked like a Rolex Sea-Dweller (Ref: 126600-0001) in stainless steel. He was all smiles afterward, and could you blame him with an extra $1.1 million in his pocket?
With respect to the watch, the Rolex Sea-Dweller was a project that started in 1967 when there was a demand for dive watches that could operate at depths of 1,000 ft. For those depths the Sea-Dweller needed something more than just a larger, more rugged case, it was the introduction of their patented the helium escape valve. That patent was more than likely the reason for these watches not being available to the public until 1971. On the side of the case, there is what looks like a button, but is actually the helium escape valve for saturation diving.
The slow decompression process was causing the crystals on the watch to pop off, so a spring-loaded valve was designed to slowly release those pressured gases. The current generation Sea-Dweller is a 43mm workhorse made from Rolex’s own 904L Oystersteel. Oystersteel offers superb corrosion resistance for deep saltwater dives and can offer a better polish than standard stainless. Sea-Dwellers offer larger hands and luminescent markers that glow up to 8hrs for easier reading underwater. The Sea-Dweller name on the black dial is in red to pay homage to the first models that had the same logo, those originals are some of the rarest Rolex models ever produced. The Sea-Dweller’s bezel is finished in Cerechrom Ceramic, an extremely durable and scratch resistant finish that should hold up to all the seawater and UV rays you can throw at it.
Inside the Sea-Dweller is Rolex’s Calibre 3235 movement that was designed in house for a high level of performance and 70 hours of power reserve. After the 3235 receives its certification from the COSC it is then installed in the case and tested a second time, by Rolex, to ensure it is operating with the precision they demand. The 3235 also features Rolex’s Chronergy escapement and Paracchrom hairspring to increase the efficiency of the movement. In 2012 a prototype Sea-Dweller DeepSea Challenge watch went down to 10,898 meters (35,754ft), the bottom of Challenger Deep of the Mariana’s Trench.
It was great to see Poston play so well on Sunday and get his first PGA Tour win! Hopefully, with that prize money, he can plan a little vacation when the season is over, to do some diving with his Rolex Sea-Dweller!
