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

The Rolex Datejust 31 ref. 278275-0030 features a 16mm lug width. This measurement, less common than the 19mm or 20mm formats found on larger Datejust models, is specific to the 31mm case family and requires aftermarket straps selected for this precise dimension.

For an Everose gold case, an alligator belly strap with a hand-polished grain — preferably in bordeaux, plum or tobacco brown — is the most aesthetically coherent choice. Shell cordovan represents an equally refined alternative, its silky sheen complementing the warm tone of Everose gold without competing with it.

To replace the strap on a Datejust 31, the two springbars housed in the case lugs must be removed using a flat or forked springbar tool. It is advisable to work on a soft surface to protect the Everose gold case from scratches, and to use professional-grade tools to avoid deforming the 16mm springbars.

Yes. The Datejust 31 ref. 278275-0030 accepts any aftermarket strap with a 16mm lug width and standard springbars. Milano Straps offers a selection of handcrafted leather, alligator and other premium material straps specifically sized for this width, with buckle or deployant clasp options in various metals including rose gold to match the Everose case perfectly.

The lifespan of a leather strap depends on the material, tanning process and daily use. A quality vegetable-tanned alligator strap, paired with a well-fitted buckle, can last between 3 and 7 years with ordinary care. Prolonged exposure to water, perspiration and UV rays accelerates deterioration; the fixed keeper is usually the first element to show wear. The Casati Milano guarantee covers 18 months against manufacturing defects.
