Frequently asked questions

What is the lug width of the Tudor Classic 21010-0002?

The Tudor Classic 21010-0002 features a lug width (ansa measurement) of 20 millimetres. This dimension represents the distance between the two strap attachment pins and determines compatibility with replacement straps. To verify it accurately, use a digital calliper positioned between the internal contact points of both spring bars: the 20mm measurement allows you to use straps specifically dimensioned for this reference.

Which strap is recommended for the Tudor Classic 21010-0002?

For the Tudor Classic 21010-0002, we recommend a genuine alligator strap or vegetable-tanned calf leather, in dark brown or black tones. Alligator complements the minimalist character of the satin-finished case with its natural and geometric grain, whilst vegetable-tanned leather develops a patina that dialogues with the passage of time. Both materials respect the restrained elegance that characterises this 38-millimetre timepiece.

How do I replace the strap on the Tudor Classic 21010-0002?

Strap replacement requires a spring bar tool (remover). Position the flat end of the tool in the groove beneath the left pin, apply gentle downward pressure until the pin retracts, then extract the old strap. Repeat on the right side. Insert the pins of your new 20mm strap into the corresponding seats on the case, pressing until you hear a click. Verify that the strap is correctly secured before wearing the watch.

Can I use an aftermarket strap on the Tudor Classic 21010-0002?

Yes, any strap with a 20mm lug width is mechanically compatible with the Tudor Classic 21010-0002. However, we recommend selecting high-quality materials (alligator, vegetable-tanned calf, shell cordovan) that respect the aesthetic restraint of this dress watch. Premium leather straps also guarantee greater durability and positive ageing over time, an essential aspect for a timepiece of this calibre.

How long does a leather strap last on the Tudor Classic 21010-0002?

The lifespan of a leather strap depends on material quality, daily use, and maintenance. An artisanal vegetable-tanned calf or shell cordovan strap, used daily, maintains full functionality for 18–24 months before showing significant wear signs. Excellent-quality alligator can last 24–36 months. Proper exposure management (avoiding prolonged moisture), regular cleaning with specific products, and careful handling substantially extend your strap's serviceable life.
