Strap for Datejust 31 Rolesor Yellow Fluted Diamond / Jubilee / Champagne Roman

The Rolex Datejust 31 reference 178313-0072 features a 31mm case with a lug width of 16mm. This measurement can be verified by placing a digital calliper between the lugs with the strap removed.

For this two-tone Datejust 31 in Oystersteel and yellow gold, the most fitting choice is a 16mm alligator strap in vegetable-tanned leather or a shell cordovan strap. The natural grain of the reptile leather complements the fluted yellow gold bezel, while a deployant clasp balances the visual weight of the case.

The strap on the Rolex Datejust 31 is secured via 16mm spring bars fitted into the case lugs. A pointed spring bar tool is sufficient to compress the bars and release the strap. It is advisable to work on a padded surface to avoid scratching the case.

Yes. Any strap with a 16mm lug width and standard spring bars is compatible with the Datejust 31. Milano Straps offers a curated selection of handcrafted 16mm straps in alligator, calfskin, shell cordovan and other materials, with bespoke finishing by Casati Milano atelier.

The lifespan of a leather strap depends on material quality and daily care. A high-grade vegetable-tanned alligator strap, used regularly but kept away from water, perfume and prolonged perspiration, will typically last between 2 and 5 years. Shell cordovan, owing to its dense fibre structure, generally offers superior longevity.
