The Rolex Datejust Ref. 116231BKDO features a stainless steel case paired with an elegant 18K Everose gold oyster bracelet featuring center links. It boasts a fixed fluted bezel made of the same 18K Everose gold, and a sophisticated black dial accented by rose gold-tone hands and diamond hour markers at each position for enhanced aesthetics. This analog watch includes date functionality visible through the aperture at the 3 o'clock position. Powered by the automatic Rolex calibre 3135 movement with a 50-hour power reserve, it is equipped with scratch-resistant sapphire crystal to ensure durability and clarity. The screw-down crown allows for water resistance up to 100 meters (approx. 330 feet), suitable for swimming but not professional diving. The solid case back offers full visibility of the inner workings. With its classic round 36mm diameter case, equipped with an Oysterlock clasp mechanism and a fixed fluted bezel, this timepiece delivers exceptional luxury watch performance including accurate hour, minute, second, and date display. It is Swiss Made.
