Strap for Datejust 31 Rolesor Everose Fluted / Oyster / White Diamond

The lug width of the Rolex Datejust 31 178271-0039 is 16 millimetres. This measurement is essential for selecting a compatible strap. You can verify it by measuring the internal distance between the lug holes using a digital calliper, or by consulting the Rolex warranty documentation.

The 178271-0039, thanks to its Everose bi-colour finish (steel and rose gold), pairs beautifully with alligator leather in warm tones (cognac, tobacco, honey brown), vegetable-tanned calf for a vintage character, or shell cordovan for those seeking durability and patina development. For more active use, fabric NATO or translucent rubber ensure practicality without aesthetic compromise.

Strap replacement requires the extraction of the spring bars (small metal pins) that secure the strap to the case lugs. Rolex provides specialist tools, though an authorised service centre is recommended to prevent damage. Alternatively, an experienced strap artisan (such as those at Milano Straps) can execute the change with precision, verifying alignment and dimensional compatibility.

Yes, provided the strap is constructed for a 16-millimetre lug width. Milano Straps offers a specialised collection of artisan straps compatible with this dimension, crafted from fine leathers (alligator, calf, shell cordovan) and manufactured to Haute Couture standards. Each strap carries an 18-month warranty against production defects.

Longevity depends on material choice, daily usage, and maintenance. Vegetable-tanned calf, worn moderately (3–4 days weekly), typically lasts 4–6 years. Shell cordovan, owing to its fibrous density, can reach 8–10 years. Alligator sits in the mid-range (6–7 years). Periodic cleaning with a soft cloth and storage away from heat sources substantially extend service life.
