Frequently asked questions

What is the exact lug width of the Rolex Daytona 116505-0013?

The Rolex Daytona 116505-0013 is equipped with 20-millimetre lugs. This measurement must be verified with a digital calliper positioned perpendicularly to the case lugs, with an acceptable tolerance between 19.8 and 20.2 mm. Do not rely on visual measurement alone, as precision is essential to avoid damage to the rose gold case.

Which type of strap is most suitable for the Daytona 116505-0013 in rose gold?

For the Daytona 116505-0013, alligator (particularly Porosus grade in chocolate or cognac shades) represents the ideal choice both aesthetically and constructively. Alligator ages beautifully with wear and complements the warm tones of rose gold. Valid alternatives include full-grain calf leather in dark brown and burgundy shell cordovan. Vegetable-tanned calf leather offers a compromise between aesthetics and everyday versatility.

How do I change the strap on a Rolex Daytona without damaging the case?

To change the strap on the Daytona 116505-0013, position the watch on a soft support (non-fraying cotton cloth). Use a dedicated spring bar tool and proceed with gentle, parallel movements to the case, avoiding lateral pressure. The rose gold case is relatively delicate: it is strongly recommended either to entrust the operation to an expert or to request a pre-mounted strap with compatible deployant from Casati Milano, which mounts with precision and no risk of scratching.

Can I fit a generic 20mm aftermarket strap to my Daytona 116505-0013?

No, it is not advisable. Although the measurement is 20mm, generic straps often present insufficient construction tolerances and may damage the lugs and spring bars of the rose gold 18-carat case. Milanostraps.it artisanal straps are calibrated specifically for the Daytona and available with Rolex-compatible deployants, ensuring precise compatibility and total reversibility without risk.

How long does a leather strap last on a Daytona?

A quality leather strap (alligator, full-grain calf, shell cordovan) typically lasts 3–5 years with moderate daily wear, or 5–7 years with occasional wear. Longevity depends on exposure to moisture, direct sunlight, and sweat pH. Casati Milano straps, crafted from excellent European vegetable-tanned leathers, tend to last at the upper end of this range and develop an aged patina that increases visual character over time.
