Strap for Datejust 31 Yellow Gold Domed / President / Champagne Floral

The lug width of the Rolex Datejust 31 ref. 178248-0093 is 16 millimetres. This measurement represents the internal distance between the two attachment points of the case where the strap is inserted. To verify correctly, use a digital calliper and measure at the upper part of the case, between the inner edges of the two lugs.

For the Datejust 31 in 18-carat yellow gold, alligator is the most aristocratic choice, particularly Porosus alligator with regular texture and luminous patina that dialogues splendidly with the gold. Excellent alternatives include shell cordovan for the purist, which develops a fascinating patina over time, or vegetable-tanned calf leather for those who prefer sustainability and comfort. Each material imparts a different character to the timepiece, allowing versatility of use.

Changing the strap on the Datejust 31 requires precision. Position the watch on a soft surface, locate the terminal lugs and use a spring bar tool to gently compress the internal spring. Once the lugs are freed, the old strap slides away. For installation of the new strap, align the holes in the lug with the case pins and press until the spring engages again. We recommend maximum caution: if inexperienced, entrust this task to a specialist watchmaker.

Yes, any strap with a 16mm lug width is theoretically compatible. However, to preserve the aesthetic integrity of the 178248-0093 in yellow gold, we recommend bespoke artisanal straps that respect the proportions of the model. Our 16mm Rolex straps are designed considering case thickness, overall length and colour matching with yellow gold, guaranteeing proportional harmony.

A high-quality leather strap (alligator, shell cordovan, calf) has an average lifespan of 3-5 years with daily wear, extendable to 7-10 years with proper care. Maintenance is minimal: keep the leather dry, avoid prolonged exposure to sun and water, and occasionally apply a specific watch leather protector balm. The natural patina that develops over time is desirable, not a flaw. Rolex recommends periodic replacement to keep the strap in optimal condition.
