Frequently asked questions

What is the lug width of the Rolex Daytona 126519LN-0007?

The Rolex Daytona 126519LN-0007 features a 20-millimetre lug width. This measurement represents the distance between the two lugs at the case attachment point for the strap. All 20mm straps are fully compatible with this model.

What is the best strap for the Daytona 126519LN-0007?

For a white gold and ceramic Daytona, genuine alligator in brown tones—cognac or deep chocolate—represents the most refined choice. Genuine alligator offers regular grain, superior durability, and a patina that evolves with time. Alternatively, Italian box calf with vegetable tanning guarantees artisanal character and dignified ageing.

How do you change the strap on a Rolex Daytona?

The strap is changed by removing the spring bars that connect the strap to the lugs. Use a dedicated strap-changing tool—a small one—to gently lever the pins, remove them, and insert those of the new strap. If you are inexperienced, rely on an authorised Rolex service centre or a specialist atelier such as Casati Milano.

Can I use an aftermarket strap on this Daytona?

Yes, provided the lug width is 20mm. High-quality artisanal straps from independent manufacturers fit perfectly. We recommend choosing premium materials—alligator, vegetable-tanned calf, shell cordovan—to respect the construction level of the watch and ensure durability over time.

How long does a leather strap last on a Rolex?

A high-quality leather strap with vegetable tanning typically lasts an average of 3–5 years with regular use, whilst developing a beautiful patina. Alligator tends to last longer (5–7 years) thanks to its scaly structure. Lifespan depends on use, climate, and periodic maintenance. Casati Milano guarantees 18 months against manufacturing defects.
