The Steel Case Rolex Sea-Dweller 4000 Replica Watch Ref. 116600 case is water resistant to 1220 meters versus the 300 meters of the Submariner, and sports a thicker case and sapphire crystal. While most people who dive won’t really need that extra water resistance, Rolex like to make its diving watches suitable for the most extreme conditions.
Still sporting a 40mm case in 904L steel, a date display with no magnifier and 4000 ft (1220 M) of water resistance, the 116600 keeps up with the modern line-up thanks to the inclusion of a Cerachrom bezel and a Gildelock clasp with a 26mm diving extension on the bracelet.
In many ways the new Rolex Sea-Dweller 4000 Replica Watch is similar to the Rolex Submariner, but after a few months working out at the gym to bulk up. An excellent example of what people mean when they say “tool watch,” the Rolex Sea-Dweller is is the stuff of dive watch legend, and Rolex didn’t mess with the established formula for this updated version. Thanks to input from the US Navy (via the SEALAB II program) and French Comex divers, Rolex designed a watch that was capable of withstanding extreme pressure and expelling the helium gas that can seep into the case during a saturation dive.
The Rolex Sea-Dweller Replica Watch considerable water resistance is thanks to a case and crystal that is thicker than that of the Submariner and firmly places the resistance of the Rolex Sea-Dweller between the 1000 ft Submariner and the 12,800 ft DeepSea. This might be an extra watch model for a niche group of consumers or the model that is akin to the right temperature porridge if you want to use the Goldilocks analogy.
Sporting the same Rolex 3135 movement that is found in the 116610 Submariner Date, the Rolex Sea-Dweller 4000 Ref. 116600 has a power reserve of 48 hours and features a Parachrom hairspring and COSC certification. Having said that, from a purely aesthetic standpoint a great benefit of the Rolex Replica Watch over the Rolex Submariner Date, is that you get to have the inclusion of a date window, without having the sapphire crystal magnifier lens on the crystal. The Rolex Sea-Dweller was originally launched in 1967 as a response to the expanding world of saturation diving.
