The Rolex Rolex Deepsea (ref. 136668LB) is an automatic diver watch, with a 44mm 18 kt yellow gold case, 5.5mm thick, powered by the 3235 movement and a 70-hour power reserve. Water resistance is rated to 3900m, under a sapphire crystal, with date complications. Manufacturer MSRP is $68,100.
Owners widely praise the Rolex Deepsea for its robust build and serious capability, with one owner calling it "bulletproof" and surprisingly less large than it appears. Reviewers note subtle aesthetic updates and refined case and bracelet for improved comfort, alongside the modern 3235 movement offering a 70-hour power reserve and running at +2 seconds per day. Some owners find its size too large for daily wear, though it serves as a good conversation piece. On balance, owners and reviewers rate the Rolex Deepsea highly for its impressive engineering and robust build quality.
