Rolex Lady-Datejust 31 31 mm 278271CDO Steel/Rose Gold Chocolate

The Rolex Lady-Datejust 31 in reference 278271CDO is one of the most refined expressions in Rolex's storied Datejust family, presenting a 31 mm case that sits gracefully between the brand's smaller and larger date-display models. Since the Datejust's debut in 1945 as the first self-winding waterproof wristwatch to feature a date display, the collection has evolved into an enduring symbol of understated prestige. The Lady-Datejust 31 inherits every element of that legacy while offering a proportion that flatters a wide range of wrists.

The 31 mm Oyster case of reference 278271CDO is crafted from a combination of Rolex's proprietary Oystersteel—a corrosion-resistant 904L steel alloy—and 18k Everose gold, Rolex's own rose-gold formula developed for long-lasting color stability. The contrast between the cool, polished steel case flanks and the warm Everose gold crown and bezel gives this reference a two-tone character that is at once classic and contemporary, echoing the brand's celebrated Rolesor tradition.

At the center of attention is the chocolate dial, a deep, warm brown surface set with diamonds that catch light with every movement of the wrist. The color chocolate has proven one of the most sought-after dial treatments in the Lady-Datejust lineup, offering a warmer and rarer alternative to the more common black or white dials. The 18k Everose gold fluted bezel frames the dial with an architectural scalloped edge that is among Rolex's most iconic design signatures, historically serving a functional purpose and today retained as a hallmark of refined aesthetics.

Power comes from Rolex's proprietary automatic movement, which offers the precision and reliability that underpin the brand's global reputation. The movement is housed within the triple-lock Oyster case, which Rolex rates to 100 meters (330 feet) of water resistance, ensuring the watch is entirely at home in everyday environments from the office to casual water exposure. The Oyster bracelet further reinforces this wearability, providing secure, comfortable wear with Rolex's characteristic brushed and polished link finishing.

For the discerning buyer, the Lady-Datejust 31 ref. 278271CDO represents a smart acquisition: a two-tone Everose gold and steel Rolex with a diamond dial in one of the most desirable dial colors on the market.
