Rolex Datejust 31 31 mm 278344RBRPSO Steel/White Gold/Diamonds Pink

The Rolex Datejust is one of the most storied references in the history of Swiss watchmaking, and the 31 mm case size occupies a sweet spot that has attracted a devoted following since Rolex expanded the Datejust family to serve a wider range of wrist profiles. Reference 278344RBRPSO represents one of the most refined expressions of that lineage, pairing precious white gold and Oystersteel construction with diamonds for a result that is simultaneously sporty and genuinely glamorous.

At 31 mm, the case is crafted in Rolex's proprietary Oystersteel, a 904L stainless steel alloy prized for its exceptional corrosion resistance and its ability to hold a high-polish finish over years of daily wear. The case is complemented by 18k white gold crown guards and case elements, giving the two-tone composition a crisp, cool-toned contrast that photographs beautifully and reads as unapologetically luxurious on the wrist.

The pink dial is the emotional heart of this reference. Soft yet confident, the blush hue plays against the diamond-set white gold domed bezel in a way that feels both feminine and boldly architectural. Hour markers are presented as clean indexes set against the pink background, ensuring legibility while preserving the dial's elegant, uncluttered aesthetic. The combination of the pink dial with sparkling diamond bezel is precisely what makes the 278344RBRPSO one of the most searched Datejust 31 configurations among buyers today.

Power comes from an automatic movement, consistent with Rolex's commitment to self-winding mechanical precision across the Datejust range. The watch is water resistant to 100 meters, reflecting the Oyster case's hermetically sealed construction and underscoring that this is a genuine instrument watch, not merely a decorative piece. The Oyster bracelet completes the package with the brand's signature three-link architecture, offering a secure and comfortable fit that integrates seamlessly with the steel and white gold case.
