What I'm asked about the Tudor Royal 28500-0001

What strap size does the Tudor Royal 28500-0001 take?

The Tudor Royal 28500-0001 needs 20 mm between the lugs, usually 16 mm at the buckle. It's the size I've been fitting on it for years.

Can the strap on the Tudor Royal 28500-0001 be changed?

Yes. It has spring bars between the lugs: with the right tool the strap comes off in a minute. If you'd rather not risk a scratch, I do it in the workshop.

Can I put a leather strap on the Tudor Royal 28500-0001?

Yes, in 20 mm leather. On a 38 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Tudor Royal 28500-0001?

A 20 mm calf strap, for every day. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.

Frequently asked questions

What strap is best suited for the Tudor Royal 28500-0001?

The Tudor Royal 28500-0001 pairs beautifully with alligator leather straps in dark brown or black tones, which emphasise the classical character of the stainless steel case. Vegetable-tanned calf represents an elegant alternative for formal contexts, whilst a cotton NATO strap provides daily versatility. Your choice depends on intended use and desired aesthetic profile.

Can I use a non-original strap on the Tudor Royal 28500-0001?

Absolutely. A quality aftermarket strap—in alligator, calf, or rubber—offers superior versatility compared to the original strap, allowing you to adapt the watch to multiple contexts. Ensure the lug width is precisely 20mm to guarantee correct fit and structural longevity of the strap over time.

What is the expected lifespan of a leather strap on the Tudor Royal 28500-0001?

Strap longevity depends on material quality, frequency of wear, and environmental conditions. A premium alligator strap can remain functional for 3–5 years of daily use; vegetable-tanned calf typically lasts 2–4 years. Exposure to perspiration, moisture, and UV radiation accelerates ageing. Proper maintenance—regular drying and annual conditioning—significantly extends lifespan.

The next step
