Rolex Datejust 31 31 mm 278240PRJ Steel Pink

The Rolex Datejust 31 reference 278240PRJ is a certified authentic, brand-new example of one of watchmaking's most storied lines — a 31mm stainless steel dress-sport watch that arrives at Bizak & Co. dressed in a soft pink dial, stainless steel domed bezel, and the celebrated five-link Jubilee bracelet. First introduced in 1945 as the world's first self-winding wristwatch to display the date in a window at 3 o'clock, the Datejust has spent eight decades defining what a modern classic looks like on the wrist. The 31mm case size occupies the sweet spot between Rolex's 28mm Datejust and the full 36mm, making it a thoroughly versatile size that suits a wide range of wrists and wears equally well dressed up or down.

The case and bracelet of the 278240PRJ are crafted entirely from stainless steel — specifically Rolex's proprietary 904L Oystersteel, an alloy prized for its exceptional corrosion resistance, hardness, and ability to hold a high polish for years of daily wear. The Oyster case construction, synonymous with the Datejust lineage, provides robust protection for the movement within and contributes to the watch's 100-meter (330-foot) water resistance rating. The screw-down Triplock crown secures the case hermetically, a hallmark of Rolex engineering reliability.

The pink dial is the defining aesthetic element of this reference. In the Datejust family, dial color plays an enormous role in character and collectibility, and pink has long been associated with the line's most sought-after and romantic configurations. The sunburst finish typical of Rolex lacquered dials catches light with a gentle warmth, making the dial appear to shift in tone from blush to deeper rose depending on the environment. Hour markers and hands finished in white gold-toned metal provide crisp legibility against the pink ground, while the signature Cyclops lens over the date aperture magnifies the date 2.5× for easy reading.

The stainless steel domed bezel frames the dial with understated elegance. Unlike the sport bezels found on the Submariner or GMT-Master II, the Datejust's domed bezel is a pure dress element — smooth, polished, and designed to let the dial speak. Paired with the Jubilee bracelet — a five-link design originally created by Rolex in 1945 specifically for the Datejust's debut — the watch drapes naturally on the wrist, combining flexibility with a refined, dressy silhouette that remains instantly recognizable.

At its heart, the 278240PRJ houses an automatic movement, continuing the Datejust tradition of self-winding mechanical excellence. Rolex's modern Datejust calibers are COSC-certified chronometers and regulated in-house to a higher standard still, a commitment to precision engineering that underpins every watch the brand produces. The movement charges through the motion of the wearer's wrist, eliminating the need for manual winding during normal daily wear.
