Strap for Datejust 31 Yellow Gold Diamond / Oyster / Champagne Diamonds Rubies

The Rolex Datejust 31 reference 178288-0062 has a lug width of 16mm. This measurement is taken with a digital calliper placed between the two lugs, perpendicular to the case. It differs from the 20mm found on the Datejust 36 and is specific to the 31mm case diameter. A 16mm strap is therefore mandatory for a correct fit.

For a yellow gold Datejust 31, an alligator belly strap in cognac, chocolate or bordeaux tones is the most coherent choice with the warmth of the precious metal. Vegetable-tanned calf leather is ideal for those seeking a progressive patina. For casual or sporting contexts, a technical nylon NATO or vulcanised rubber strap provides durability without adding weight. A deployant clasp reduces stress on the stitching and ensures repeatable precision when fastening.

Strap replacement on the Datejust 31 178288-0062 requires a spring bar tool (bifurcated tip) inserted into the channel cut laterally into each lug. Compress the spring bar, slide out the original strap and reverse the process to fit the new one. Care is required to avoid scratching the yellow gold case: protecting it with low-tack masking tape or entrusting the operation to a watchmaker is strongly advisable.

Yes. Standard 16mm aftermarket straps with spring bar attachment are fully compatible with the Rolex Datejust 31 178288-0062. Milano Straps offers handcrafted 16mm straps in alligator, calf, shell cordovan and nylon, with customisable taper. There is no need to purchase genuine Rolex straps: compatibility depends solely on the attachment width, not the strap brand.

The lifespan of a leather strap depends on the material, maintenance and frequency of wear. A quality alligator strap, regularly conditioned and stored away from heat sources, typically lasts 3–5 years with daily use. Vegetable-tanned calf leather develops a characteristic patina and may last 2–4 years. Prolonged exposure to perspiration, water and UV rays accelerates deterioration. Milano Straps products carry an 18-month warranty against manufacturing defects.
