Pre-owned Rolex Sea-Dweller ref 126660B (2019), better known as the James Cameron or “D-Blue,” is one of the more distinctive modern Rolex dive watches. The gradient dial fades from deep blue into black, a tribute to James Cameron’s 2012 descent into the Mariana Trench, and it’s a look that stands apart from anything else in the lineup. The 44mm Oyster case is made for serious depth, rated to 3,900 meters, with Rolex’s Ringlock system and a helium escape valve to handle extreme pressure. It also features a Cerachrom ceramic bezel and Chromalight display for strong low-light visibility. Inside is the caliber 3235 with a longer 70-hour power reserve. Rolex discontinued this model in 2022, but it’s still widely sought-after by collectors in the know. Shop Rolex Sea-Dweller Collection
