Strap for Datejust 31 Stainless Steel/ Rose Gold / Fluted / Chocolate - Roman / Oyster

The Rolex Datejust 31 ref. 278271-0003 has a lug width of 16mm. This measurement should be taken internally between the two lugs using a digital calliper, positioned parallel to the case back. It is specific to this 31mm configuration and is not interchangeable with other Datejust diameters.

For the Datejust 31 in Everose Rolesor, an alligator belly-cut or shell cordovan strap is the most coherent choice given the formal register of the timepiece. Vegetable-tanned calf leather develops a unique patina over time that harmonises naturally with the rose gold. For sporting contexts, a vulcanised rubber strap with curved ends offers functional comfort without compromising the watch's aesthetic.

To replace the strap on a Datejust 31, a fine-tipped springbar tool is required. Rolex lugs feature lateral access holes for the spring bars. Insert the tool into the hole, compress the spring bar and slide out the existing strap. Care should be taken to avoid scratching the rose gold lugs; applying Kapton tape to the lug area before working is strongly recommended.

Yes. Aftermarket straps with a 16mm attachment and end pieces shaped to match the geometry of Rolex lugs are compatible with the ref. 278271-0003. Milano Straps offers a range of handcrafted straps in various leathers and rubber, available bespoke or ready to ship, fitted with buckles or deployant clasps suited to the 16mm width.

Longevity depends on the material and conditions of use. A high-quality alligator strap, with moderate daily wear and proper care, typically lasts 2 to 4 years. Shell cordovan, being denser and more resistant to surface moisture, can exceed 4 years. Vegetable-tanned calf leather is more sensitive to perspiration and benefits from regular rotation. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
