Strap for Datejust 31 Stainless Steel / Yellow Gold / Diamond / White - Roman / Oyster

The lug width of the Rolex Datejust 31 reference 278383rbr-0001 is 16mm. This measurement refers to the internal distance between the two lugs at the strap attachment point and must be respected to the millimetre to ensure a correct and secure fitting.

For the Datejust 31 in yellow Rolesor, the most suitable straps are alligator belly or hornback in cognac, burgundy or black tones, or vegetable-tanned calf leather for those who appreciate a natural patina over time. Shell cordovan is an outstanding choice for fibre density and longevity. All straps must feature a 16mm attachment.

To replace the strap on the Datejust 31, a spring bar tool is required to release the spring bars from the case lugs. This can be carried out carefully by the wearer, or entrusted to a watchmaker or the Casati Milano atelier to ensure correct installation without risk of scratching the case.

Yes, high-quality aftermarket straps compatible with the Datejust 31 are available, specifically crafted with a 16mm attachment. Milano Straps offers a curated selection of artisan leather, rubber and other material straps, all produced with precise lug measurements to guarantee compatibility and build quality commensurate with the watch.

The lifespan of a leather strap depends on the material, care and daily usage. A quality artisan alligator or shell cordovan strap, with regular maintenance (nourishing cream, protection from water), can last between 3 and 7 years. Milano Straps provides an 18-month warranty covering manufacturing defects.
