Strap for Datejust 31 Rose Gold / Domed / Grey / Oyster

The lug width of the Rolex Datejust 31 ref. 278245-0025 is 16mm. This measurement should be taken with a digital calliper between the two lugs at the narrowest point, flush against the case middle of the Everose gold case. Always use straps with a precise 16mm end-piece to avoid lateral play or stress on the keeper.

For the Datejust 31 in Everose gold, a vegetable-tanned Mississippiensis alligator strap paired with a rose gold deployant clasp is the most formally coherent choice. Shell cordovan in cognac develops a warm patina that naturally complements the Everose tones. For everyday wear, a bordeaux or mid-brown box-calf strap offers a balanced and durable pairing.

To replace the strap on a Datejust 31, remove the spring bars connecting the current bracelet or strap to the case lugs. Use a fine flat-head screwdriver or a dedicated springbar tool, applying leverage in the notch on the lug. Work on a padded surface to protect the polished Everose gold case. Insert the new 16mm strap by engaging one end of the spring bar first, then compressing the other until it clicks into place.

Yes. The Datejust 31 278245-0025 features standard 16mm lugs that accept aftermarket straps from any manufacturer adhering to this measurement. Milano Straps offers a curated selection of handcrafted leather, rubber and fabric straps specifically compatible with this model, featuring hand-finished 16mm end-pieces. Material quality and end-piece precision are critical for both aesthetics and comfort on this reference.

The lifespan of a leather strap depends on the material and usage. A quality vegetable-tanned alligator strap, with proper care, retains structural and aesthetic integrity for 3 to 5 years of regular wear. Shell cordovan, due to its dense fibre structure, tends to last even longer while developing patina. Casati Milano straps carry an 18-month warranty against manufacturing defects. To extend strap life, avoid prolonged exposure to perspiration, water and direct heat sources.
