The Rolex Datejust reference 78279B is a 31mm timepiece in Steel and Yellow Gold presented in used condition, with a Custom Black MOP Diamond dial, Fluted YG bezel, President bracelet, dated circa 1999. This piece is customized — aftermarket-modified (setting or dial added outside the manufacturer); not original factory condition. Every watch is inspected and authenticated by our specialists before it is offered, so you can buy with confidence.
Across eighty years the Datejust has stayed remarkably consistent in concept and endlessly adaptable in form. From the 1945 original through the caliber-3135 16xxx era to today's 126xxx line, the formula holds: a chronometer-grade daily wearer that dresses up easily. Metals climb from Oystersteel to Rolesor to solid gold. Whichever you favor, our authentication and guidance help you commit without second-guessing. Read the full Datejust buying guide ›
Hans Wilsdorf founded Rolex in 1905, and the Geneva manufacture has since become the benchmark against which most mechanical watches are judged. Its engineers pioneered waterproofing, self-winding movements, and date displays, building a reputation for precision and durability. Before you buy, our desk verifies the Oyster case, the Perpetual movement, and the Cyclops lens. With supply trailing demand, steel sports references often trade above retail, so confirmed authentication matters. Browse all Rolex ›
