Strap for Datejust 31 Rose Gold / Fluted / Chocolate - Diamond / Oyster

The Rolex Datejust 31 ref. 278275-0017 has a lug width of 16mm. This measurement refers to the internal distance between the two lugs at the case root and is the decisive parameter for selecting any compatible aftermarket strap.

For an Everose Gold case, wide-grain alligator leather in bordeaux, mahogany or cognac tones represents the most coherent pairing in terms of noble materials. Shell cordovan is a more compact and structured alternative. In both cases, a deployant clasp in rose gold completes the ensemble without visual interruption.

The Rolex Datejust 31 uses a standard spring bar system with 16mm lug width. To replace the strap, a spring bar tool is required to remove the bars connecting the strap to the case lugs. Care must be taken to avoid scratches on the Everose Gold case; if in doubt, it is advisable to consult a watchmaker or specialist atelier.

Yes. Any strap with a 16mm lug width and standard spring bars is technically compatible with this model. Milano Straps offers handcrafted straps in alligator, calf, shell cordovan and FKM rubber specifically made for 16mm lugs, with finishes and clasps selectable according to the case aesthetic.

The longevity of a leather strap depends on the quality of the hide, the tanning process and daily use. A high-quality alligator or shell cordovan strap, with regular care (conditioning with neutral products and rotation between multiple straps), maintains structural and aesthetic integrity for 3 to 7 years. Vegetable-tanned straps develop a patina over time, increasing their aesthetic value with wear.
