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

The Rolex Datejust is widely regarded as the archetypal dress watch, and the 31mm case size—introduced to satisfy demand for a refined, mid-sized timepiece—has become one of the collection's most enduring and beloved expressions. First launched in 1945 as the world's first self-winding wristwatch to display the date in a window at 3 o'clock, the Datejust has evolved continuously while preserving the design cues that made it iconic. Reference 278344RBRPSJ sits firmly in the modern generation of the line, marrying classic Rolex architecture with luxurious material choices that reward close inspection.

The case of the 278344RBRPSJ measures a versatile 31mm in diameter, crafted from a combination of Oystersteel—Rolex's proprietary corrosion-resistant alloy—and 18k white gold. This two-tone construction adds warmth and prestige to the profile without overwhelming the watch's inherently understated proportions. The Oyster case provides robust protection, and the timepiece is rated to 100 meters (330 feet) of water resistance, making it far more capable than most dress watches of comparable elegance.

At the heart of this reference's visual appeal is its pink dial, a color that has surged in popularity among collectors and style-conscious buyers alike. Diamond hour markers replace traditional applied indices, scattering light across the dial and lending the piece a jewellery-like brilliance. Crowning the dial is a white gold domed bezel set with brilliant-cut diamonds, a detail that elevates the 278344RBRPSJ firmly into the realm of gem-set Rolex references that command lasting desirability on both primary and secondary markets.

The Jubilee bracelet—one of Rolex's most storied bracelet designs, debuted alongside the very first Datejust in 1945—grounds the watch in its historical context while delivering a supple, five-piece link construction that drapes beautifully on the wrist. Its fine finish complements the polished and satin surfaces of the Oystersteel and white gold case, creating a seamlessly unified aesthetic. The Jubilee remains the quintessential pairing for the Datejust, and on the 278344RBRPSJ it feels entirely correct.

Powering the watch is an automatic movement, ensuring the convenience of self-winding reliability that Rolex movements are celebrated for worldwide. The date complication—displayed through the iconic cyclops lens magnifier at 3 o'clock—remains as practical as it is symbolic of the Datejust lineage.
