Strap for Datejust 31 Yellow Gold Domed / President / Silver Roman

The Rolex Datejust 31 reference 178248-0083 has a lug width of 16mm. This measurement should be taken with a calliper at the internal distance between the two lugs at the base of the case. It is essential to use straps with an exact 16mm fitting to avoid lateral play or stress on the spring bar holes.

For the Datejust 31 178248-0083 in yellow gold, an alligator strap with vegetable tanning in dark brown or cognac is the most coherent choice with the formal and elegant register of the watch. Smooth box calf leather is ideal for versatile everyday wear, while shell cordovan offers a contemporary high-character profile. For sporting contexts, vulcanised rubber is the most functional solution.

The strap on the Rolex Datejust 31 is replaced using a springbar tool with a fine tip. Insert the tip into the lug hole, compress the spring bar and slide the strap out laterally. Care should be taken not to scratch the yellow gold case; it is advisable to work on a soft surface and, if in doubt, to consult a watchmaker or the Casati Milano atelier.

Yes. Aftermarket straps compatible with the Rolex Datejust 31 178248-0083 must have a 16mm fitting and standard spring bars of 1.5mm diameter. Milano Straps offers a selection of handcrafted straps in various materials — alligator, calf leather, shell cordovan, rubber — made specifically for this lug width, with bespoke craftsmanship available at the Casati Milano atelier.

The lifespan of a leather strap depends on the material, care and daily use. A quality vegetable-tanned alligator strap, rotated periodically and stored away from moisture and heat sources, retains its aesthetic and structural properties for 3–5 years of regular use. Perspiration and water are the main factors of deterioration: it is advisable not to wear a leather strap in aquatic environments. Milano Straps guarantees its straps for 18 months against manufacturing defects.
