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

The Rolex Datejust 31 reference 278285rbr-0015 has a lug width of 16 mm, measured internally between the lug walls at the six o'clock side. This is the dimension required when ordering any compatible aftermarket strap.

For a Datejust 31 in Everose gold, a vegetable-tanned alligator strap in cognac, burgundy or dark olive is the most coherent choice for the watch's dress register. Box calf leather is a versatile option for everyday use, while vulcanised rubber suits sportier settings without compromising the overall aesthetic.

To replace the strap on a Rolex Datejust 31, you need a fine-tipped spring bar tool. Insert the tool into the lug slot, compress the spring bar pin and slide the strap free. Take care not to scratch the gold case; if this is your first time, it is advisable to consult a watchmaker or contact the Casati Milano atelier.

Yes. The 16 mm lug width of the Datejust 31 is supported by a curated selection of artisan aftermarket straps available on milanostraps.it, including alligator, calf leather, shell cordovan, rubber and NATO nylon options, with bespoke tailoring available through the Casati Milano atelier.

The lifespan of a leather strap depends on the material, care routine and frequency of use. A quality vegetable-tanned alligator strap, kept away from water and treated periodically with conditioning cream, can last between 3 and 7 years whilst retaining its patina and structure. Box calf leather typically lasts 2 to 4 years. Casati Milano provides an 18-month guarantee against manufacturing defects.
