At the heart of the Rolex Datejust 279383RBR lies the perpetual, self-winding Caliber 2236 movement, a feat of modern horological engineering that represents Rolex's commitment to precision in their women's timepiece collection. This 28mm yellow gold and Oystersteel Rolesor case houses a movement equipped with Rolex's proprietary Syloxi hairspring, delivering enhanced resistance to shocks and temperature variations that serious collectors demand. The white mother-of-pearl dial creates an luminous backdrop for diamond hour markers, while the diamond-set bezel adds 44 brilliant-cut diamonds that catch light with every gesture. Reference 279383RBR exemplifies the contemporary Lady-Datejust evolution, combining traditional proportions with cutting-edge materials and manufacturing techniques.
