For the first time in Rolex history, the fake Sea-Dweller is available in two-tone tones. The patented two-tone coating as Yellow Rolesor combines 904L Oystersteel steel with 18-carat yellow gold and reveals it as an incredibly flexible coating suitable for any occasion or activity. The Sea-Dweller was developed as a saturation diver and also includes a unidirectional timing hoop equipped with a flexible Cerachrom ceramic insert, a Chromalight bright Maxi selector, and a water-resistant Triplock crown up to 4,000 feet. The Helium Leak Valve is also vital to the impressive water-resistance of the Sea-Dweller as it allows the gases that have accumulated in the case to escape without peeling off the crystal. The new Sea-Dweller model is powered by a brand new 3235 caliber drive, complete with a new Chronergy getaway and a larger 70-hour power supply. The culmination of decades of the specialized Rolex replica watch, the Sea-Dweller 126603 has since become one of the newest additions to the brand catalog.
