Back in 1945, the Datejust set the template: the first self-winding waterproof chronometer to show the date under that magnified Cyclops. Four case sizes, steel through Rolesor to solid gold, and a dial palette that runs almost endless. It sits as Rolex's most accessible and most versatile reference at once. Pricing runs $3,539 to $32,200, and the steel 36mm 126234 trades with the liquidity dealers count on. Read the full Datejust buying guide ›
Hans Wilsdorf started this in 1905, and the Geneva manufacture has set the standard for mechanical watches ever since. Rolex pioneered waterproofing, self-winding movements, and the date display, building a name on precision and durability. The Oyster case, Perpetual movement, and Cyclops lens are known worldwide. Steel sport references like the Submariner, GMT-Master II, and Daytona trade above retail, so wire pricing puts real money back in your pocket. Browse all Rolex ›
