Rolex Datejust Lady 31 31 mm 278240SDBO Steel/White Gold/Diamonds Silver Rolex Datejust Lady 31 31 mm 278240SDBO…

The Rolex Datejust Lady 31 is one of the most enduring timepieces in horological history, tracing its lineage to 1945 when Rolex introduced the world's first self-changing date wristwatch. The Lady 31 midsize variant occupies a refined sweet spot in the collection, offering a 31mm case that wears with understated authority on a wide range of wrists. Reference 278240SDBO represents this legacy at its most polished, pairing the clean lines of the Datejust with an opulent custom diamond bezel and a silver dial that catches and reflects light with quiet brilliance.

The case of the 278240SDBO is constructed in Oystersteel — Rolex's proprietary 904L stainless steel alloy known for its exceptional resistance to corrosion and its mirror-bright polish — complemented by 18k white gold accents. This combination of metals is a hallmark of the Datejust family, providing both durability and a sense of elevated luxury that few other references can match at this size. The integration of white gold with Oystersteel gives the watch a seamlessly cool, precious tone throughout.

The bezel of this reference is custom-set with diamonds, transforming what is already a refined sports-dress watch into a genuinely jewel-like statement piece. Against this sparkling frame, the silver dial reads with clarity and elegance, its polished surface lending depth and dimension. The Oyster bracelet — Rolex's most iconic and robust link design — ties the watch together in a fluid, finished silhouette that wears comfortably and securely.

Powering the watch is an automatic movement, consistent with the Datejust line's commitment to precision and reliability. The case provides 100 meters (330 feet) of water resistance courtesy of the legendary Oyster case construction, which uses a screw-down crown and case back to create a hermetically sealed environment for the movement. This means the 278240SDBO is not merely a display piece — it is a fully capable daily companion.
