Strap for Datejust 31 Stainless Steel/ Rose Gold / Domed / Rose - Diamond / Jubilee

The Rolex Datejust 31 ref. 278241-0024 has a lug width of 16mm. This is the correct measurement to use when selecting any aftermarket strap compatible with this reference.

For the Datejust 31 278241-0024 in Oystersteel and Everose gold, a vegetable-tanned alligator strap in cognac or tobacco tones is the most coherent choice aesthetically. Box calf leather and shell cordovan are strong alternatives for those who prefer a tighter, more refined grain. A deployant clasp in rose gold ensures maximum formal consistency with the case materials.

Strap replacement on the Datejust 31 is carried out using standard 16mm spring bars. A dedicated spring bar tool and a watch cushion are recommended to avoid scratching the Everose gold case. Alternatively, the operation can be performed at the Casati Milano atelier during a scheduled appointment.

Yes. Any strap with a 16mm lug width is technically compatible with the Rolex Datejust 31 278241-0024. Milano Straps offers a dedicated selection of 16mm straps in various materials — alligator, calf leather, shell cordovan, NATO, and rubber — all crafted with end-pieces precisely cut to the declared lug width.

Strap longevity depends on the material, tanning method, and frequency of wear. A quality vegetable-tanned alligator strap, with standard care, typically lasts between 2 and 4 years under regular daily use. Shell cordovan, due to its dense, compact structure, tends to last considerably longer. Milano Straps products carry an 18-month warranty against manufacturing defects.
