Frequently asked questions

What is the lug width of the Rolex Day-Date 36 ref. 1802 Qaboos?

The lug width of the Rolex Day-Date 36 1802 Qaboos is exactly 20 millimetres. This measurement is determined by calculating the distance between the two pins (lugs) on which the strap is attached. Measuring the lug width correctly is fundamental to guarantee compatibility with quality aftermarket straps.

Which type of strap is most suitable for a Rolex Day-Date 36 1802 Qaboos in white gold?

For an 1802 Qaboos in 18-carat white gold, alligator remains the most elegant and classical choice, thanks to its fine grain and aesthetic compatibility with the precious metal. Alternatively, vegetable-tanned calf leather offers a natural patina that ages magnificently, or shell cordovan for those seeking superior constructive density and marked texture. For daily wear, robust cotton NATO straps provide a practical solution without formal compromises.

How do you change the strap on a Rolex Day-Date 36 1802 Qaboos?

Changing the strap on an 1802 Qaboos requires attention. Use a specific tool to extract the pins (the two metal fasteners connecting strap and lug): insert the tool into the small lateral hole of the lug and push gently until the pin exits. Repeat for both sides. Insert the pins into the new strap and reinsert them into the lugs with reverse movement. If you are unsure, entrust the task to a certified watchmaker.

Is a quality aftermarket strap compatible with the Rolex Day-Date 36 1802 Qaboos?

Yes, completely. An artisanal 20mm strap from specialised manufacturers such as Casati Milano is entirely compatible with the 1802 Qaboos. Compatibility depends solely on lug width (20mm) and pin type (straight or curved). By choosing a strap constructed with premium leather and artisanal craftsmanship, you can enhance the overall comfort and aesthetics of your watch.

How long does a leather strap typically last on a Rolex Day-Date 36?

The durability of a leather strap depends on the material, usage and construction quality. Premium alligator typically resists 3-4 years with daily wear. Vegetable-tanned calf leather, if frequently exposed to sun, can last 2-3 years but improves in patina over time. Shell cordovan is the most robust (up to 5-6 years). Casati Milano's warranty on manufacturing defects covers 18 months. To extend durability, avoid prolonged exposure to humidity and direct sunlight, and occasionally apply protective balms specific to watch leather.
