Rolex Day-Date 36 36 mm 118388SDO Yellow Gold/Diamonds Silver

The Rolex Day-Date has held a singular place in horological history since its debut in 1956, becoming the first wristwatch to display both the date and the full day of the week spelled out on the dial. Reserved exclusively for precious metals, the Day-Date has long been associated with heads of state, executives, and tastemakers worldwide — earning its enduring nickname, the "President's Watch." The 36mm case size remains true to the original proportions of this legendary reference, honoring the model's storied heritage while delivering a wrist presence that suits a wide range of wearers.

Reference 118388SDO takes the Day-Date's inherent prestige several steps further by pairing an 18k yellow gold construction with an extensive diamond treatment across the bezel and case. The result is an extraordinarily luminous watch that catches the light from every angle. The silver dial provides a cool, refined contrast to the warm glow of the yellow gold and the scintillating diamonds, creating a visual balance that feels both opulent and purposeful.

The diamond-set bezel on the 118388SDO is one of its defining characteristics, replacing the classic fluted or smooth Rolex bezel with individually hand-selected stones set to exacting standards. Rolex's in-house gem-setting artisans meticulously evaluate each diamond for cut, clarity, color, and carat weight before placement, ensuring the continuous brilliance that defines a genuine Rolex diamond reference. The diamonds set into the case sides further amplify this effect, making the 118388SDO unmistakably distinctive among even the most refined watch collections.

The watch is powered by Rolex's automatic movement, delivering the reliable, precise timekeeping the brand is universally celebrated for. Housed within the robust 18k yellow gold Oyster case, the movement benefits from Rolex's legendary engineering standards, offering the wearer confidence in both accuracy and long-term durability. The Oyster bracelet — one of the most recognized and ergonomic bracelet designs in watchmaking — completes the package with fluid articulation and a secure, comfortable fit on the wrist.
