Pre-owned Rolex Sea-Dweller ref 126603 (2022) is the first iteration of the famed deep saturation diver to sport a steel and gold finish. Previously, the collection was only produced in stainless steel. This is a significant upgrade as collectors opt to wear sports watches as more of a statement piece rather than as a practical tool. Ref. 126603 is a renowned dive watch in the watchmaking industry because it couples a Helium Escape Valve with Rolex’s celebrated Triplock screw-down crown to protect the case from depths of up to 4,000 feet. As a modern watch, it also sports a uni-directional time-lapse bezel outfitted with a ceramic insert, a Maxi dial with larger hour markers and hands filled with long-lasting Chromalight, scratch-resistant sapphire, and the next-generation caliber 3235 Perpetual movement.
