What I'm asked about the A. Lange & Söhne 1815 234.042

What strap size does the A. Lange & Söhne 1815 234.042 take?

The A. Lange & Söhne 1815 234.042 needs 20 mm between the lugs. It's the size I've been fitting on it for years.

Can the strap on the A. Lange & Söhne 1815 234.042 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 234.042?

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 1815 234.042?

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.
