Frequently asked questions

What is the exact lug width of the Rolex Daytona 126505?

The Rolex Daytona ref. 126505 has a lug width of 20mm, determined by the distance between the case lugs that support the strap. To measure correctly, use a digital calliper on the inner lugs, excluding the case itself. Any 20mm strap is compatible with this reference.

Which strap do you recommend for the Daytona 126505 in Everose?

For the 126505 in Everose gold, American alligator is the traditional choice: fine grain complements the metal without competing visually. Shell cordovan offers density and patina development parallel to Everose. Vegetable tanning appeals to those seeking constructive authenticity and textured appearance. Polished calf is practical for daily wear. Avoid saturated colours; select warm brown, deep black, anthracite grey, or burgundy instead.

How do I change the strap on my Rolex Daytona 126505?

Strap removal requires a dedicated spring bar tool. Position your watch on a soft cloth, locate the small access holes beneath the lugs, insert the tool with precision and gently push until the pin disengages. Repeat on both sides. Proceed with extreme care; Rolex cases do not tolerate damage from improper tools. If inexperienced, contact an authorised Rolex service centre.

Can I use a quality aftermarket strap on my Daytona 126505?

Absolutely. A quality 20mm aftermarket strap, crafted from premium materials such as alligator, shell cordovan or calf, is perfectly compatible. Verify that the lugs are proportionate to the 40mm case and that the spring bar loop is appropriate. A well-made artisanal strap does not compromise the watch's value and allows personalisation that original Rolex straps do not permit.

How long does a leather strap last on a Daytona 126505 with daily use?

A premium leather strap, featuring vegetable tanning or shell cordovan, lasts 3–5 years with daily wear. Alligator and polished calf have comparable lifespans. Longevity depends on perspiration, sun exposure and maintenance: apply leather balm every 6–8 months and store the watch away when not worn. Casati Milano straps, backed by an 18-month manufacturing warranty, are built to exceed this timeframe if maintained properly.
