The Rolex Day-Date ref. 18239, introduced in the late 1980s, marked an important evolution for the storied model. Along with other contemporaneous references, the ref. 18239 incorporated upgrades that enhanced both robustness and practicality - hallmarks of the Rolex brand. Most significantly, it was powered by the new cal. 3155, Rolex's first movement to feature a double quick-set function. This mechanism allowed for rapid adjustment of both the day and date indications via the crown - a major convenience for wearers.

By the late 1980s, the Day-Date had already cemented its status as an enduring icon following its debut in 1956. Nicknamed the "President's Watch," it had accrued prestige and renown as the timepiece of choice for presidents, CEOs, and dignitaries across generations. Consequently, any changes to such a historic reference from Rolex were bound to generate interest amongst collectors and aficionados.

And interest has certainly flourished in recent times, as the Day-Date enjoys resurgent popularity among modern collectors. The present ref. 18239 from circa 1990 with a “E” serial number embodies an excellent example of unpolished case with sharp edges. Its sunburst silver dial harmonizes elegantly with diamond-set indexes, conveying subtle luxury. Sleek and versatile, this Day-Date exemplifies the enduring appeal of Rolex's masterful design.
