Rolex Day-Date President 18078

Reference 18078 identifies the ‘bark’ finish Day-Date 36 from the 180xx series, produced from approximately 1978 to 1988. This reference is built on the platform that introduced two key technical modernizations: a scratch-resistant sapphire crystal and the Caliber 3055. This 27-jewel automatic movement features a ‘single quickset’ mechanism, enabling rapid correction of the date display via the crown. The 36mm Oyster case is constructed from 18k yellow gold (8) and is distinguished by its ‘bark’ bezel (7), an intricate, hand-applied texture resembling wood grain. This finish was frequently extended to the center links of the 18k gold President bracelet. The 18078 is historically significant as it carried a classic, artisanal Rolex finish into the modern quickset era.
