About this watch
Rolex Steel and Yellow Gold Datejust 31 Watch - Diamond Bezel - Mother-of-Pearl Diamond Dial - Jubilee Bracelet - 278383RBR mdj
Powered by Rolex's caliber 2236 automatic movement with its distinctive Syloxi hairspring, the Rolex Datejust 278383RBR delivers 55 hours of power reserve within its 31mm yellow gold case—a technical achievement that positions this reference among the most refined expressions of contemporary horological engineering. The mother-of-pearl dial foundation showcases ten diamond hour markers, creating depth and luminosity that shifts with ambient light conditions. Diamond-set bezels on Datejust references represent Rolex's commitment to gem-setting excellence, with each stone precisely calibrated for maximum brilliance. This unworn example demonstrates the meticulous attention to detail that defines the modern Datejust collection's approach to luxury sports watch design.
