Strap for Cosmograph Daytona Everose / Cerachrom / Chocolate / Oysterflex

The Rolex Daytona 116515LN-0015 features a lug width of 20 millimetres. This is the standard lug width for modern Daytona models since Rolex adopted the 40mm case diameter. Measurement is taken with a digital calliper between the internal lugs (lug-to-lug distance).

For this rose gold Daytona with black ceramic bezel, we recommend black or dark brown alligator leather with vegetable tanning, which naturally complements the 18-karat gold tone. Vegetable-tanned calf offers an evolving patina that creates visual dialogue with the ceramic bezel. For sporty use, an anthracite grey NATO maintains racing authenticity without compromising aesthetics.

Remove the lug pins by gently pressing a small screwdriver or spring bar tool against one end until the internal spring gives way, then extract the pin. The strap slides out of the case. Insert the new strap by passing the pins through the lugs, ensuring they click securely into the holes. If inexperienced, consult a certified watchmaker.

Yes, provided the lug width is precisely 20 millimetres and the strap is crafted from quality material (alligator, vegetable-tanned calf, FKM rubber). The buckle must be rose gold or stainless steel with a brushed or black finish for visual coherence. Milano Straps specialises in custom 20mm straps with personalised finishes.

A high-quality alligator strap lasts 8–12 years with regular wear, thanks to the inherent robustness of the leather. Vegetable-tanned calf resists 6–10 years and improves aesthetically with age. Longevity depends on wear frequency, sun exposure, humidity and care. With regular maintenance (light cleaning, drying after perspiration), you can extend strap life by 2–3 years.
