Rolex Datejust 31 31 mm 278240PSJ Steel Pink

The Rolex Datejust is widely regarded as one of the most recognizable and enduring watch designs in horological history. Introduced in 1945, the Datejust was the world's first self-winding wristwatch to display the date in a window on the dial, a feature so ahead of its time that the concept quickly became an industry standard. Decades on, the collection retains its foundational DNA while continuously refining its execution—and the Datejust 31 represents that tradition in a mid-size format that sits beautifully on a wide range of wrists.

The reference 278240PSJ measures 31 mm in diameter, a case size that occupies a refined middle ground between the brand's smaller 28 mm ladies' references and the full-size 36 mm and 41 mm sport-dresser models. The case is crafted entirely in stainless steel—Rolex's proprietary 904L Oystersteel, celebrated for its superior corrosion resistance and mirror-like polish—delivering a luxurious appearance that requires minimal maintenance over decades of ownership. With 100 meters (330 feet) of water resistance courtesy of the Oyster case architecture, this is a watch built to accompany an active life without compromise.

The pink dial of the 278240PSJ is perhaps its most captivating attribute. Rolex's dial finishing is executed in-house with extraordinary precision, and the soft, warm pink tone catches light in a way that reads as understated elegance rather than overt femininity—making it equally attractive to any wearer who appreciates refined color. The stainless steel domed bezel frames the dial with clean, classic lines, eschewing gem-setting or fluting for a look of pure, unadorned sophistication that pairs effortlessly with both casual and formal attire.

Complementing the case and dial is the iconic Jubilee bracelet, a five-piece link design that Rolex introduced alongside the very first Datejust in 1945. Its finely brushed center links contrasted with polished outer links give the wrist a fluid, jewel-like quality, and the bracelet's articulation ensures exceptional comfort throughout the day. Secured by Rolex's Oysterclasp with the EasyLink comfort extension system, it can be fine-tuned by approximately 5 mm at the clasp—a small detail that makes a significant difference in all-day wearability.

Driving the 278240PSJ is an automatic movement, ensuring this Datejust 31 winds itself through the natural motion of the wearer's wrist and delivers the self-sufficiency that modern collectors expect from a serious timepiece.
