Pre-owned Rolex Sea-Dweller ref 136660 (2025) continues the lineage of Rolex’s most capable deep-sea diver, delivering both familiar DNA and subtle refinements. Its robust 44mm Oystersteel case remains waterproof to an astonishing 3,900 meters, paired with the classic three-link Oyster bracelet and a unidirectional ceramic bezel built for saturation diving. Upgrades on this generation include a slimmer bezel profile that highlights the sapphire crystal and an enlarged date window, 8% larger for overall improved legibility. The watch also introduces RLX Titanium branding, Rolex’s proprietary designation for its caseback alloy, combining strength with reduced weight. Bright Chromalight ensures optimal legibility in the darkest depths, while the screw-down crown and solid caseback guarantee uncompromising durability. Purpose-built yet luxurious, the ref. 136660 embodies Rolex’s mastery of professional-grade engineering while retaining the everyday refinement expected of a luxury dive watch.
