Rolex Day-Date 36 36 mm 118238BSO Yellow Gold Black

The Rolex Day-Date is arguably the most prestigious watch in the Rolex catalog, introduced in 1956 as the first wristwatch to display both the date and the full day of the week spelled out in a window on the dial. From its very debut the Day-Date was crafted exclusively in precious metals — gold or platinum — and it has never deviated from that standard, making every example a statement of genuine luxury rather than a cosmetic upgrade.

Reference 118238BSO represents the 36mm generation of the Day-Date, a case size that was the sole expression of the model for decades before the 40mm variant was introduced. The 36mm Oyster case in 18k yellow gold is polished and brushed to Rolex's exacting standards, with the characteristic Oyster architecture — a monobloc middle case, screw-down crown, and screwed case back — delivering a robust and hermetically sealed package beneath that gleaming precious-metal exterior.

The black dial of this reference provides a striking and versatile backdrop that works equally well in boardroom and evening settings. Index hour markers set against the deep black surface create crisp legibility, while the day and date apertures at 12 o'clock and 3 o'clock respectively are rendered in a font that has become iconic to the Day-Date identity. The yellow gold fluted bezel frames the dial with the elegant serrated profile that Rolex originally designed to conceal and protect the case-to-bezel joint, and which has since become one of the brand's most beloved aesthetic signatures.

The Oyster bracelet on this reference completes the all-yellow-gold ensemble with a sporty yet refined link structure, offering a different character from the traditional President bracelet and giving the wearer a slightly more contemporary wrist feel. Rolex's Oysterlock safety clasp ensures the bracelet stays secure during any activity. Powered by an automatic movement, the Day-Date 118238BSO winds itself through the motion of the wrist via a Perpetual rotor, requiring no manual winding during regular wear.
