Frequently asked questions

What is the lug width of the Tudor Royal 28503-0001?

The lug width of the Tudor Royal 28503-0001 is 20mm. This width is standard for 38mm diameter watches and ensures optimal proportions between the strap and the watch case. Lug width is calculated by measuring the distance between the two barrel ends that attach the strap to the case.

What is the best strap for the Tudor Royal 28503-0001?

For the two-tone Tudor Royal 28503-0001, black alligator represents the most cohesive choice: the natural grain of Nile crocodile does not compete chromatically with yellow gold and steel, conferring formal elegance. Alternatively, shell cordovan with vegetable tanning in burgundy creates sophisticated warmth-on-warmth contrast, whilst charcoal-black calf offers versatility without compromising aesthetic integrity.

How do I change the strap on my Tudor Royal 28503-0001?

Strap replacement requires a spring bar tool with double-ended tip. Position the watch on a stable surface and use the spring bar tool to compress one lateral pin inward until the upper lug is released, then remove the old strap. Repeat on the other side. For installation of the new strap, align the holes with the lugs and press the spring bar until it clicks into position. Using screwdrivers or improvised tools is not recommended as it risks case damage.

Can I use an aftermarket strap on my Tudor 28503-0001?

Yes, any strap with a 20mm lug width is compatible with the Tudor Royal 28503-0001. The aftermarket offers numerous variants in alligator, calf, shell cordovan and synthetic materials. The essential requirement is verifying that the lug width is exactly 20mm and that the strap is sufficiently long to accommodate your wrist circumference, accounting for movement within the case's keepers.

How long does a leather strap last on the Tudor Royal 28503-0001?

The lifespan of a leather strap depends on daily use, humidity exposure and maintenance practices. With vegetable tanning and standard care (monthly cleaning, bi-annual conditioning), an alligator or calf strap can last 2–4 years. Shell cordovan, being denser, can exceed 5 years. Replacement is advisable when the strap shows significant cracking, loosening at the lugs or deterioration of the buckle/deployant, rather than on a rigid temporal schedule.
