What I'm asked about the Tudor Classic 21013-0011
What strap size does the Tudor Classic 21013-0011 take?
The Tudor Classic 21013-0011 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 Classic 21013-0011 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 Classic 21013-0011?
Yes, in 20 mm leather. On a 38 mm dress watch alligator is the natural choice: thin, elegant, what it was born for.
Which strap do you recommend for the Tudor Classic 21013-0011?
A thin 20 mm alligator. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
