Strap for Datejust 31 Rolesor Everose Domed Diamond / Oyster / Pink

The lug width of the Rolex Datejust 31 178341-0060 is precisely 16mm. This specification is critical when selecting an aftermarket strap—it must correspond exactly to ensure proper fit across the case lugs and correct assembly. Lug width is measured in the space where the lug holes sit on the case.

We recommend natural alligator in brown or burgundy for classic elegance, vegetable-tanned calf for daily patina development, or shell cordovan for superior durability. Selection depends on usage: formal, versatile, or active. All straps must feature 16mm lug width and a steel buckle (or deployante clasp) compatible with the Twinlock crown.

Strap removal requires precision tools: a steel spring bar tool and a protected work surface. Locate the spring bar hole on each lug, gently compress the spring mechanism toward the case centre, and extract the bar. Repeat on the opposite side. Insert the new strap by aligning the spring bars into the holes and press until audible click. For absolute safety, Casati Milano offers in-atelier replacement service.

Yes, any strap featuring 16mm lug width is mechanically compatible. However, aesthetic and constructive compatibility requires: standard spring bars, leather thickness consistent with case proportions, and an adjustable steel keeper. Poor-quality aftermarket straps risk damaging the case lugs over time.

Longevity varies by material: natural alligator endures 4–6 years under daily wear; vegetable-tanned calf 3–5 years; shell cordovan 5–8 years. Durability depends on solar exposure, perspiration, and maintenance habits. All Casati Milano straps include an 18-month warranty covering manufacturing defects.
