Strap for Datejust 31 Rolesor Everose Domed / Jubilee / White Roman

The lug width of the Rolex Datejust 31 reference 178241-0062 is 16mm. This is a non-standard size in the aftermarket sector: it must be verified using a digital calliper measured directly between the case lugs — not on the original bracelet — to ensure a precise fit without lateral play.

For the Datejust 31 178241-0062 in Oystersteel and Everose gold, the most coherent choices are a glossy alligator in bordeaux or cognac, which complements the warm tones of the rose gold, or a vegetable-tanned calf leather for everyday wear. For those who prefer a secure and long-lasting closure, a deployant clasp in steel or rose gold is the most refined technical solution. The correct lug width is 16mm.

To replace the strap on a Rolex Datejust 31, the spring bars securing the bracelet to the case lugs must be removed. Use a fine-tipped spring bar tool (lever or pin type), inserting the tip into the lug hole and compressing the spring inward. Work on a soft surface to protect the case. It is advisable to entrust this operation to a watchmaker or to the Casati Milano atelier to avoid scratching the two-tone case.

Yes, there are aftermarket straps compatible with the 16mm lug width of the Datejust 31 178241-0062.

The lifespan of a leather strap on a Rolex Datejust 31 depends on the material and care. A quality alligator strap, worn on rotation with a second strap, can last over 3–5 years while retaining its shape. Vegetable-tanned calf leather develops patina and lasts 2–4 years with regular use. Avoid prolonged contact with water and perspiration, and store the strap on a strap holder when not in use. Milano Straps offers an 18-month guarantee against manufacturing defects.
