Frequently asked questions

What is the lug width of the Rolex Daytona 116505-0002?

The Rolex Daytona 116505-0002 features 20mm lugs. This is the standard lug width established by Rolex for modern Daytona chronographs. Measurement is taken internally, from lug pin to lug pin. Any artisanal strap designed for 20mm lug width will be perfectly compatible with this reference, with no forcing or settling required.

Which strap is most suitable for a rose gold Rolex Daytona?

For a rose gold Daytona 116505-0002, black or deep brown alligator represents the most sophisticated choice, highlighting the warm tonality of the case. Shell cordovan, the leather from a horse's croup, offers extraordinary elegance with a personal patina developing over time. Vegetable-tanned calf provides robustness and refinement for daily wear. For a sportier aesthetic, a black or navy blue NATO creates immediate visual impact without competing with the gold.

How do you change the strap on a Rolex Daytona 116505?

The Daytona features a standard lug system: the strap attaches via spring bars that pass through the lugs of the case. To remove the strap, a dedicated tool (spring bar tool) allows you to push inward on the spring bars and slide the strap from the lugs. The procedure requires care to avoid scratching the case. Casati Milano offers personalised guidance for this operation.

Is an aftermarket strap compatible with the Rolex Daytona 116505-0002?

Yes, any artisanal strap designed for 20mm lug width is fully compatible. The Daytona's spring bars are standard, and a quality leather strap with correctly finished lugs will fit perfectly. What matters is verifying that the strap has been crafted with rigorous tolerances and respects the 20mm width specification.

How long does a leather strap last on a watch like the Daytona?

The lifespan of a leather strap depends on the material, frequency of wear, and environmental conditions. A quality artisanal alligator or shell cordovan strap, with routine maintenance (avoiding excess moisture and dirt), can last 8-15 years. Vegetable-tanned calf typically lasts 5-10 years but develops fascinating patinas. Casati Milano provides 18 months warranty on manufacturing defects and offers guidance for long-term preservation.
