Frequently asked questions

What is the lug width of the Tudor Royal 28400-0011?

The lug width of the Tudor Royal 28400-0011 is 20mm, measured between the two lateral pins that emerge from the case lugs. This standard measurement ensures compatibility with the vast majority of aftermarket straps available on the market.

Which strap is recommended for the Tudor Royal 28400-0011?

For the Tudor Royal 28400-0011, an alligator strap with fine grain accentuates the dress-watch character of the model. Alternatively, calf leather with natural patina offers versatility, whilst a shell cordovan strap in cognac colour creates a warm contrast particularly elegant against the stainless steel case.

How do I change the strap on the Tudor Royal 28400-0011?

To change the strap, use a spring bar tool (a specific tool with two metal palettes). Gently insert the palette under the lateral pin of the lug to lift the spring bar, remove the old strap, and insert the new spring bar into the strap eyeholes. Ensure the spring bar clicks correctly into the case lugs.

Is the Tudor Royal 28400-0011 compatible with quality aftermarket straps?

Yes, the 28400-0011 is perfectly compatible with quality aftermarket straps. Thanks to the standard 20mm lug width, it is possible to fit straps in alligator, calf, shell cordovan, vegetable-tanned leather and rubber from specialist brands without any case modification.

How long does a leather strap last on the Tudor Royal 28400-0011?

A quality leather strap, subject to regular maintenance (cleaning with a soft cloth and hydration with specific creams), has an average lifespan of 3–5 years with daily use. Durability depends on leather quality, intensity of use, exposure to humidity and sunlight. A shell cordovan strap tends to last longer due to fibre density.
