Frequently asked questions

What is the lug width of the Tudor Royal 28500-0001?

The Tudor Royal 28500-0001 features a lug width of 20mm. This dimension accommodates a broad range of aftermarket straps, available in both leather and synthetic materials. To verify the correct lug width, use a digital calliper positioned between the two lateral lugs on the case.

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.

How do I change the strap on the Tudor Royal 28500-0001?

Position the watch with the lugs facing upwards. Locate the small hole at the base of each lug and insert a spring bar removal tool. Press gently inward to release the spring bar, then extract the existing strap. Repeat on the opposite side. To install the new strap, align the ends with the lugs and press until you feel the spring bar seat securely.

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.
