Rolex Day-Date 36 ‘Black Dial, Factory Diamonds’ – Reference 18048

Heritage Narrative

The Rolex Day-Date reference 18048 represents one of the most luxurious executions of the brand’s flagship model during the late vintage era. Produced in solid 18k yellow gold, the 18048 builds upon the classic Day-Date formula while introducing the sapphire crystal and single quickset date, marking Rolex’s transition toward a more modern technical platform.

This example stands out with its original black dial fitted with factory diamond hour markers, paired with an original factory diamond-set yellow gold bezel. Unlike later gem-set references, these early factory diamond configurations are prized for their restrained execution and perfect balance between elegance and presence. The deep black dial provides a striking contrast against the warmth of yellow gold, giving the watch a timeless yet commanding aesthetic.

Completed with the iconic President bracelet, the Day-Date 18048 remains a symbol of achievement and authority. Highly collectible in original factory diamond configuration, this reference captures the essence of the Day-Date at its most refined — bold, confident, and unmistakably Rolex.
