What I'm asked about the A. Lange & Söhne 1815 231.031

What strap size does the A. Lange & Söhne 1815 231.031 take?

The A. Lange & Söhne 1815 231.031 needs 19 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 1815 231.031 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 1815 231.031?

Yes, in 19 mm leather. On a 36 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 1815 231.031?

A thin 19 mm alligator. You'll find it ready in the 19 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
