Strap for Datejust 31 Stainless Steel / Yellow Gold / Fluted / Black MOP / Jubilee

The Rolex Datejust 31 reference 278273-0024 has a lug width of 16mm, measured at the base of the lugs using a vernier calliper perpendicular to the case axis. This measurement is essential when selecting a compatible aftermarket strap.

For the Datejust 31 with a mother-of-pearl dial and yellow gold Rolesor case, straps in vegetable-tanned alligator or box calf leather offer the most coherent pairing with the model's aesthetic register. Shell cordovan in burgundy or cognac tones is particularly effective in complementing the warm reflections of the Rolesor. For sport or aquatic use, FKM rubber maintains full compatibility with the Oyster water resistance.

Strap replacement requires a precision springbar tool with a fine tip (0.7–0.9mm) to avoid scratching the Oystersteel lugs. The tool is inserted laterally into the springbar slot, compressing the retaining spring until the bar releases. The procedure is fully reversible and does not require an authorised service centre, but care must be taken to preserve the lug finish.

Yes. Any strap with a 16mm lug width and curved-end profile is compatible with the Datejust 31 278273-0024. Milanostraps.it offers a curated selection of handcrafted straps in this size, available as bespoke commissions or ready to purchase, with a choice of buckle or deployant clasp.

Longevity depends on the material and conditions of use. A vegetable-tanned alligator strap, properly maintained and kept away from water, excessive perspiration, and prolonged direct sunlight, will retain its structural and aesthetic integrity for 3–5 years with daily wear. Shell cordovan offers superior durability due to its dense fibre structure. Using a deployant clasp significantly reduces mechanical stress on the adjustment holes, extending the strap's service life.
