Rolex Day-Date President 18000

The Reference 18000 is an uncommon variant from the 180xx single quickset series (c. 1978-1988). Its technical specification is a 36mm case in 18k yellow gold with a smooth, polished bezel. It is mechanically identical to the 18038, housing the Caliber 3055 with its single quickset date function and featuring a sapphire crystal. The reference is significant as it often designated models supplied on a leather strap with a Rolex buckle or on an 18k gold Oyster bracelet, distinguishing it from the standard President-bracelet-equipped 18028. It represents a less common, more versatile, and understated configuration of the first quickset Day-Date generation.
