Rolex Day-Date 40 40 mm 228238BBSP Yellow Gold Black

The Rolex Day-Date 40 is widely regarded as the apex of the Rolex collection—a watch worn by heads of state, presidents, and cultural icons since its introduction in 1956. Reference 228238BBSP represents the modern evolution of this storied lineage, scaling the classic Day-Date silhouette up to a commanding 40mm case crafted entirely in 18k yellow gold. The result is a timepiece that carries more than seven decades of prestige while meeting the exacting standards of contemporary collectors.

The case of the 228238BBSP is fashioned from 18k yellow gold, polished and finished to Rolex's exacting standards. The 40mm diameter strikes an ideal balance between the classic proportions the Day-Date has always been known for and the bolder aesthetic sensibility of modern luxury watches. Water resistance of 100 meters (330 feet) ensures the watch is more than capable of handling everyday wear, a reminder that even Rolex's most prestigious references are built with genuine durability in mind.

The bright black dial is the defining visual statement of this particular reference. Deep, lustrous, and immaculately finished, the black surface creates a striking contrast against the warm yellow gold of the case, hands, and index hour markers. The dial also displays the hallmark day and date complications—the full spelling of the day of the week in a window at 12 o'clock and the date at 3 o'clock—that have made the Day-Date an enduring symbol of achievement.

The yellow gold fluted bezel is one of the most iconic design elements in all of watchmaking, its precisely machined ridges catching the light and amplifying the watch's presence. Paired with the equally legendary President bracelet—a three-piece link design exclusive to the Day-Date and crafted here in 18k yellow gold—the overall package is one of total cohesion. Every element of the 228238BBSP reinforces the same message: this is a watch built without compromise.

Powering the 228238BBSP is a Rolex automatic movement, a self-winding caliber that benefits from Rolex's decades of in-house movement development and rigorous testing. The movement ensures precise, reliable timekeeping across all conditions, an essential quality in a watch intended to accompany its owner through the most demanding days.
