Frequently asked questions

What is the lug width of the Rolex Daytona 116505-0008?

The lug width of the Rolex Daytona 116505-0008 is exactly 20 millimetres. This measurement is taken between the inner shoulders of the case from one spring bar pin to the other. A strap of incorrect width will not fit properly and will compromise both the ergonomics and aesthetics of the watch. To verify, position a ruler between the two lugs and ensure the distance is precisely 20mm.

What is the best strap material for a Rolex Daytona 116505-0008?

Alligator (Nile crocodile) is the most sophisticated choice for the Daytona 116505-0008 in rose gold: uniform grain texture complements the case without visual competition, and chromatic legibility is optimal. As an alternative, vegetable-tanned calf offers noble patina that develops over time, whilst shell cordovan conveys craftsmanship with a uniquely crystalline surface structure. For sporty application, a cotton NATO strap restores the original functional DNA. FKM rubber remains a modern technical option for daily wear.

How do I safely change the strap on a Daytona 116505-0008?

Use a spring bar removal tool specifically designed for luxury watches. Position the watch on a soft surface (microfibre cloth), locate the small vertical hole beneath the lug, insert the tool and gently push the pin downward. The lug will disengage. Repeat on the other side. Install the new strap by threading the spring bar pins first, then verify that the terminals are properly aligned with the case. If you prefer to avoid any risk, contact Casati Milano for professional installation.

Is an aftermarket strap compatible with the Daytona 116505-0008?

Yes, provided the lug width is precisely 20 millimetres. Many artisanal quality straps (alligator, calf, cordovan) are available in this standard width. Always verify with the supplier that the strap is specifically dimensioned for 20mm and that the terminals are crafted from stainless steel or precious metal to prevent reaction with the rose gold case. Casati Milano provides personalised consultation for strap selection.

How long does a natural leather strap last on a Daytona 116505-0008?

A quality artisanal leather strap typically lasts 3–5 years under intensive daily use, with variability depending on climate, perspiration and maintenance. Alligator generally lasts longer (up to 7 years) compared to calf, whilst shell cordovan ages nobly. Longevity increases significantly with regular maintenance: monthly cleaning with a damp cloth, complete drying after perspiration contact, and storage away from direct sunlight. Casati Milano offers an 18-month warranty against manufacturing defects.
