Rolex Steel and Yellow Gold Datejust 31 Watch - Domed Bezel - Dark Mother-of-Pearl Diamond Dial - Jubilee Bracelet - 278243 dkmdj

At the heart of the Rolex Datejust 278243 beats the caliber 2236, a self-winding movement that represents Rolex's latest generation of feminine mechanical engineering with its silicon Syloxi hairspring and extended 55-hour power reserve. This 31mm configuration showcases the mesmerizing interplay between brushed Oystersteel and polished 18ct yellow gold, creating the signature Rolesor aesthetic that has defined luxury sports watches since 1933. The dark mother-of-pearl dial surface captures light with an organic depth that varies dramatically throughout the day, while ten brilliant-cut diamonds replace the hour markers at positions 1, 2, 4, 5, 7, 8, 10, and 11. Reference 278243 represents the current-generation Datejust 31, featuring Rolex's most advanced case construction and hermetically sealed Twinlock winding crown.
