The Rolex Datejust is without a doubt one of the most emblematic watches of the Rolex Collection. Rolex is considered a pioneer of numerous innovations. Back in 1945, the Geneva watch manufacturer launched the Oyster Perpetual Datejust. As simple as it can be, the quick changing date is a milestone in the development of watches. The Datejust was the first self-winding waterproof chronometer wristwatch to display the date in a small window at 3 o’clock on the dial. The Datejust stands out because of its delicate and gentle round lines and its audacious yet delicate design. This Rolex Datejust 278344 is presented with a 31mm white Rolesor case comprised of Oystersteel and 18K white gold, screw-down back, screw-down crown with twinlock double waterproofness system, 18K white gold domed bezel set with diamonds, scratch-resistant sapphire crystal with cyclops lens over the date, dark grey dial, diamond hour markers.
