Datejust 31

The Rolex Datejust 31 reference 278271 pairs a 31 mm Oyster case in Rolex's proprietary two-material combination of Oystersteel and Everose gold with the manufacture's in-house Calibre 2236. Sitting at the mid-point of the Datejust size range, the reference occupies a versatile position between the classic 28 mm and the full 36 mm, appealing to collectors who favour a refined, dress-oriented proportion. A broad palette of dial options — including sundust, rosé, and aubergine — underscores the model's emphasis on personal expression within a rigorously engineered case.

The Datejust lineage traces back to 1945, making it one of the longest-running and most recognisable watch lines in horological history. The 31 mm case size formalised a middle tier within the Datejust family, and reference 278271 was introduced in 2018 as part of Rolex's broader rationalisation of the Datejust range. The pairing of Oystersteel with Everose gold — Rolex's proprietary 18 ct rose-gold alloy formulated for exceptional fade resistance — places the 278271 in the two-tone tradition that has been a hallmark of the Datejust since the mid-twentieth century. Calibre 2236, introduced specifically for the 31 mm Datejust, incorporates a Syloxi silicon hairspring and carries a Superlative Chronometer certification, reflecting Rolex's continued investment in movement development for this segment of the collection.
