Rolex Day-Date 36 36 mm 118348BSO Yellow Gold/Diamonds Black

The Rolex Day-Date is, by any measure, the ultimate expression of the Swiss watchmaker's prestige and craftsmanship. Introduced in 1956, the Day-Date was the first wristwatch to display both the day of the week spelled out in full and the date—a complication that earned it an enduring place at the wrist of world leaders, statespeople, and tastemakers across generations. Today, the Day-Date 36 upholds that storied legacy in every detail.

Reference 118348BSO occupies a particularly distinguished position within the Day-Date 36 lineup. Crafted entirely in 18k yellow gold—Rolex's own proprietary alloy—the case measures a versatile 36mm in diameter, a size that reads with authority on a range of wrist sizes and carries decades of Day-Date heritage. The warm, rich tone of yellow gold lends the watch an unmistakably classic character that transcends trends.

The black dial of the 118348BSO creates a powerful visual contrast against the luminosity of the yellow gold case and the scintillating diamond-set bezel. The dial's index hour markers anchor the design with clean legibility, while the bezel's diamond setting adds a layer of opulence that elevates this reference well beyond a standard dress watch. The result is a timepiece that commands attention in every light.

Propelling the Day-Date 36 is an automatic movement, the hallmark of Rolex's commitment to mechanical excellence. The watch is water-resistant to 100 meters (330 feet), underscoring the robustness of the Oyster case—Rolex's legendary hermetically sealed construction that has protected movements since 1926. The Oyster bracelet, finished in matching 18k yellow gold, completes the ensemble with integrated comfort and the security of Rolex's folding Crownclasp system.
