What I'm asked about the A. Lange & Söhne Saxonia 310.221

What strap size does the A. Lange & Söhne Saxonia 310.221 take?

The A. Lange & Söhne Saxonia 310.221 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 A. Lange & Söhne Saxonia 310.221 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 A. Lange & Söhne Saxonia 310.221?

Yes, in 20 mm leather. On a 39 mm dress watch alligator is the natural choice: thin, elegant, what it was born for.

Which strap do you recommend for the A. Lange & Söhne Saxonia 310.221?

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.
