Look at the generations and the value logic gets simple. 1945 set the format, the 1600s defined the 60s and 70s, the 16xxx caliber-3135 dominated the 80s and 90s, mid-2000s added the ladies 178xxx and 179xxx, and 2016 brought the current 126xxx with Syloxi hairsprings. Each era trades at its own level. Entry steel ladies to solid gold tops out the $3,539 to $32,200 range. Read the full Datejust buying guide ›
Think of a Rolex as both a watch and a position you can exit. The 1905 Geneva manufacture, started by Hans Wilsdorf, pioneered waterproof cases, self-winding movements, and date functions, earning a precision reputation that runs past horology. The Oyster, Perpetual movement, and Cyclops lens need no introduction. Submariners, GMT-Master IIs, and Daytonas in steel trade above retail, which is why wire-versus-card savings change your real cost. Browse all Rolex ›
