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

The lug width of the Rolex Datejust 31 reference 278285rbr-0022 is 16mm. This measurement refers to the internal distance between the two lugs of the case, i.e. the strap attachment width. It is advisable to verify this with a digital calliper to ensure a precise, millimetre-accurate replacement.

For the Datejust 31 in Everose gold, a vegetable-tanned alligator strap is the most coherent choice given the prestige of the timepiece: the natural grain and ability to develop an authentic patina integrate seamlessly with the precious case. Shell cordovan offers a compact, formally refined alternative. A deployant clasp in rose gold completes the pairing with full metallic consistency.

Strap replacement requires a fine-tipped spring bar tool to release the spring bars housed within the case lugs. For a Datejust in Everose gold with curved lugs and precious finishing, it is recommended to work on a soft surface and, if inexperienced, to entrust the operation to a watchmaker or the Casati Milano atelier to avoid scratching the case.

The lifespan of a leather strap on a Datejust 31 depends on the material and care. A vegetable-tanned alligator strap, with periodic conditioning and regular rotation, can last between 3 and 5 years while retaining structural and aesthetic integrity. Shell cordovan, due to its dense fibre structure, tends to last even longer. Milano Straps provides an 18-month guarantee on manufacturing defects for all its straps.
