Strap for Datejust 31 Rose Gold / Domed / Rose - Roman / President

The lug width of this model is exactly 16 millimetres. This measurement must be verified using a digital calliper positioned perpendicularly between the two case lugs, excluding any passing bars or retention rings. It is essential for excluding standard 18mm or 20mm straps and guaranteeing a perfect fit.

For Everose gold on the Datejust 31, alligator represents the classic choice par excellence, with natural quarters that dialogue visually with the case. Vegetable-tanned calf offers softer aesthetics and develops amber patina over time. Natural rubber remains ideal for daily versatility. Shell cordovan fascinates those who accept radical aesthetic evolution: patina tends toward black-brown after 6-12 months of wear.

The Datejust 31 uses standard 16mm spring bars. Using specific tools (microscopic screwdriver or dedicated tool), one compresses a lateral spring to extract the bar, then inserts the new bar into the alternative strap. Rolex recommends using an authorised service centre, although many owners manage the operation independently with care.

Yes, provided the strap is specifically constructed for 16mm lug width and the overall proportions (thickness, buckle width) respect the balance of the 31mm case. Milano Straps offers bespoke artisanal straps and a dedicated compatible catalogue for this measurement, constructed to specifications identical to original Rolex straps.

With moderate to intensive use and regular maintenance (occasional cleaning, avoiding prolonged humidity exposure), an alligator or calf strap lasts 3-5 years before requiring replacement or restoration. Natural rubber resists 4-6 years. These periods extend with occasional wear. Tanning quality and leather thickness significantly influence longevity.
