Rolex Sea-Dweller 126600

About This Watch

The Rolex Sea-Dweller 126600 bridges the gap between the Submariner and the massive Deepsea, offering professional-grade dive capability in a more wearable package. With water resistance to 1,220 meters (4,000 feet), it far exceeds the Submariner's 300-meter rating while maintaining a case size that, at 43mm, is only slightly larger. The Sea-Dweller was originally developed in the late 1960s in collaboration with COMEX, the French deep-sea diving company, to withstand the extreme pressures encountered during saturation diving operations. The ref. 126600, released in 2017 for the model's 50th anniversary, controversially added a Cyclops lens magnifier to the date window, something previous Sea-Dwellers had never featured. The helium escape valve at 9 o'clock allows helium atoms that penetrate the case during saturation diving to safely vent during decompression. The caliber 3235 provides a 70-hour power reserve, and the Fliplock extension system on the bracelet allows it to be worn over a diving suit. The Cerachrom ceramic bezel insert features platinum-coated numerals for excellent underwater legibility. For divers and watch enthusiasts who want more capability than a Submariner without the wrist-dominating proportions of the Deepsea, the Sea-Dweller is the perfect middle ground.
