Daytona 116520-0015— lug 20mm

The Rolex Daytona 116520-0015 is equipped with 20 mm lug width. This measurement is standard for the model and must be respected strictly when purchasing an aftermarket replacement strap. Always verify that the internal lug slot corresponds exactly to 20 mm before ordering your replacement strap.

There is no single best answer—it depends on usage and aesthetic preference. Mississippi alligator provides formal elegance and durability; vegetable tanning develops a splendid patina over time; Italian calf offers a balance between practicality and refinement; technical rubber is the most functional choice for continuous sport use. Casati Milano guides you through personalised consultation at the Milan atelier.

Strap replacement is a straightforward operation requiring a specific tool (spring bar removal tool). Position the watch on a stable support, locate the metal pin securing the strap to the lug, and gently extract it using the appropriate tool (provided by Rolex). Insert the new strap, aligning it with the guides, and reinsert the pin. Avoid forcing: every movement must be smooth and precise. If inexperienced, consult a certified watchmaker.

Yes, provided it is crafted for the 20 mm lug width specification. Certified aftermarket straps (such as those by Casati Milano) guarantee structural compatibility and artisanal construction that does not compromise the watch's value. Always select reputable suppliers who understand luxury strap craftsmanship and offer manufacturing warranty.

A quality leather strap worn regularly on a chronograph like the 116520-0015 has an average lifespan of 3–5 years, depending on wear frequency and environmental conditions (humidity, perspiration, sun exposure). Vegetable-tanned leather tends to last longer as the skin remains naturally elastic; chemically treated straps may harden and break sooner. Periodic maintenance (gentle cleaning, hydration) extends strap life by approximately 30–40%.
