Rolex Oysterquartz Day-Date 19048

The Rolex Oysterquartz Day-Date ref. 19048 was produced from approximately 1977 to 2001 and represents one of the most luxurious executions of the Oysterquartz line. Constructed entirely in 18k yellow gold, this model shares the same 36 mm angular case and integrated bracelet structure as other Oysterquartz Day-Date models, but is distinguished by a diamond-set bezel. It is powered by the Rolex Caliber 5055 quartz movement, offering COSC-certified precision, a 50-hour battery life, and instantaneous day and date functionality. The case thickness is approximately 13 mm, with a lug-to-lug measurement of 44 mm and a lug width of 19 mm. The bracelet is the integrated President-style design, often seen with polished center links and concealed clasp. Dials were typically offered in champagne or onyx, sometimes with factory diamond hour markers, emphasizing the luxury orientation of this reference. As part of the exclusive Oysterquartz Day-Date lineup, the 19048 is coveted for its opulent design, technical innovation, and rarity—especially with original diamond-set components. It remains a collector’s piece that reflects both Rolex’s experimentation with quartz and their commitment to uncompromising elegance.
