The Rolex Datejust 36 reference 116234 represents a refined evolution of the classic Datejust. It features a 36mm Oyster case crafted from 904L stainless steel with an 18k white gold fluted bezel, a combination that delivers the robustness of professional-grade steel with the subtle luxury of precious metal accents. This model creates a two-tone aesthetic that bridges the gap between sporty and dressy timepieces. It is powered by the Rolex Calibre 3135, a self-winding mechanical movement certified as a Superlative Chronometer, offering precision of -2/+2 seconds per day and approximately a 48-hour power reserve. The blue Parachrom hairspring provides ten times greater accuracy than a traditional hairspring in case of temperature variations or shocks. The scratch-resistant sapphire crystal includes the Cyclops magnifier over the date window at 3 o'clock. The 116234 is available with either the classic Oyster bracelet or the elegant Jubilee bracelet, both in steel. It has a water resistance of 100 meters.
