Strap for Datejust 31 Stainless Steel Fluted / Oyster / Pink - Roman

The Rolex Datejust 31 reference 278274-0023 has a lug width of 16 mm. This measurement is specific to the 31 mm case and requires straps with a 16 mm attachment for correct compatibility and balanced visual proportions relative to the case.

For the Datejust 31 in white gold and steel, an alligator strap in vegetable-tanned leather is the most coherent choice with the formal character of the watch. Smooth or padded calf leather is an excellent alternative for everyday wear. In both cases, a deployant clasp is recommended to preserve the leather over time. Casati Milano bespoke straps are crafted specifically for this reference.

The strap on the Datejust 31 is removed using a spring bar tool to release the spring bars from the lugs. This is a delicate operation: to avoid scratching the white gold case or the Oystersteel, it is advisable to entrust the task to a qualified watchmaker or skilled craftsman. The lug width of the 278274-0023 is 16 mm.

Yes. Any strap with a 16 mm attachment is technically compatible with the Datejust 31 278274-0023. Milano Straps offers a curated selection of handcrafted straps in alligator, calf leather, shell cordovan and NATO fabric, specifically selected for this lug width. Materials and finishes are chosen to complement the bicolour white gold and steel case aesthetically.

The lifespan of a leather strap depends on the quality of the hide, the tanning method and daily use. A high-quality vegetable-tanned alligator strap, properly maintained and fitted with a deployant clasp to reduce fold stress, can last between 3 and 7 years while retaining an excellent appearance. Avoiding prolonged exposure to water, perspiration and direct UV rays significantly extends the life of the strap.
