Strap for Datejust 31 Stainless Steel / Yellow Gold / Diamond / Champagne - Diamond / Oyster

The Rolex Datejust 31 reference 278383rbr-0025 has a lug width of 16mm. This measurement is the essential parameter when selecting a compatible strap: any replacement strap must have an end width of exactly 16mm to ensure a precise fit and correct aesthetics between the lugs of the yellow Rolesor case.

For a Datejust 31 in steel and yellow gold with a diamond-set bezel, a Louisiane alligator strap in vegetable-tanned leather is the most coherent choice in terms of aesthetics and longevity. Cognac, dark brown or midnight blue tones pair naturally with the Rolesor combination. Shell cordovan is an outstanding alternative for those seeking a strap that develops a distinguished patina over time. For more active use, a satin-finish vulcanised rubber strap maintains the Oyster character of the model.

Replacing the strap on a Datejust 31 requires a dedicated spring bar tool or a flat-head screwdriver with a protected tip to remove the spring bars securing the strap to the lugs. It is advisable to work on a soft surface to avoid scratching the case. Alternatively, Casati Milano offers a strap fitting service at their atelier by appointment.

Yes: any strap with a 16mm end width and standard spring bars is technically compatible with the Datejust 31 ref. 278383rbr-0025. Milano Straps offers handcrafted leather, rubber and nylon straps specifically curated for this lug width, with stitching, finishes and buckles chosen to complement the aesthetic of a Rolex watch in yellow Rolesor.

The lifespan of a leather strap depends on the material, frequency of wear and maintenance. A quality vegetable-tanned alligator strap, kept away from prolonged moisture and treated periodically with a conditioning cream, typically lasts between 3 and 5 years with daily wear. Shell cordovan can exceed 5 years, developing a sought-after patina in the process. Casati Milano provides an 18-month guarantee against manufacturing defects on all their straps.
