Rolex Day-Date President 18238

Reference 18238 identifies the archetypal Day-Date 36 from the 182xx series, which was in production from 1988 to c. 2000. This series is defined by a major mechanical upgrade to the watch’s core complication. The watch is powered by the Rolex Caliber 3155, a 31-jewel COSC-certified chronometer. The historical significance of this caliber is its introduction of the ‘double quickset’ complication, allowing both the day and date displays to be rapidly and independently adjusted via the crown. The 36mm Oyster case is constructed from 18k yellow gold (8) with a fluted bezel (3) and retains the classic case proportions of the five-digit references. It is significant as the first instance of the most iconic Day-Date configuration paired with a fully independent quickset movement.
