Rolex Day-Date President 18389

The Reference 18389 is a factory gem-set model from the Day-Date 18xxx series, produced from the late 1980s to c. 2000. This reference’s technical configuration specifies a 36mm case constructed from 18k white gold (9), with a factory diamond-set bezel and diamond-set lugs (38 code). It is powered by the Caliber 3155, a high-performance movement featuring the “double quickset” function that allows for independent, rapid setting of the day and date wheels. This reference is historically significant as it combines the advanced functionality of the then-new Cal. 3155 with extensive factory gem-setting on the classic, slimmer-lug Day-Date case. It was often paired with premium pavé diamond dials, making it a premier luxury offering of its generation.
