Rolex Day-Date President 18049

The Reference 18049 is a rare factory gem-set model from the 180xx single quickset generation, produced c. 1978-1988. The technical specification, denoted by the 49 suffix, is a 36mm case in 18k white gold (9) with a factory-set brilliant-cut diamond bezel (4). This reference is the direct successor to the non-quickset white gold diamond Day-Date, introducing two key technical upgrades: a scratch-resistant sapphire crystal and the Caliber 3055 movement with its single quickset date function. The 18049 is historically significant as the modernized version of the classic white gold diamond Day-Date, offering improved durability and user convenience in a discreetly luxurious package.
