Strap for Datejust 31 Rolesor Yellow Fluted / Oyster / White Roman

The Rolex Datejust 31 ref. 178273-0072 has a lug width of 16mm. This measurement refers to the internal distance between the case lugs and is the essential parameter when selecting a compatible replacement strap. It is advisable to verify the measurement with a digital calliper before purchasing.

For the Datejust 31 ref. 178273-0072 in Rolesor (steel and yellow gold), the most suitable options are a vegetable-tanned alligator strap with belly or hornback grain — which complements the gold elements — or a smooth box-calf leather for a more understated look. A deployant clasp matched to the gold tone completes the aesthetic without altering the watch's identity.

To replace the strap, remove the spring bars from the lugs using a dedicated forked screwdriver or a spring bar tool. Care must be taken to avoid scratching the yellow gold and steel case. It is recommended to work on a soft surface and, if inexperienced, to entrust the operation to a watchmaker or specialised atelier.

Yes. High-quality aftermarket 16mm straps are fully compatible with the Datejust 31 ref. 178273-0072, provided the heel profile and spring bar length are correct for this reference. Milano Straps offers a selection of handcrafted 16mm straps designed for this model, available online or customisable through the Casati Milano atelier.

The lifespan of a leather strap depends on the quality of the tanning, daily use and the care given to the material. A high-grade vegetable-tanned alligator strap, worn regularly, can last between 2 and 5 years while retaining its patina and structure. Avoiding prolonged contact with water and perspiration significantly extends the strap's life. Milano Straps provides an 18-month warranty against manufacturing defects.
