What I'm asked about the Jaeger-LeCoultre Duomètre 6012521

What strap size does the Jaeger-LeCoultre Duomètre 6012521 take?

The Jaeger-LeCoultre Duomètre 6012521 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 Jaeger-LeCoultre Duomètre 6012521 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 Jaeger-LeCoultre Duomètre 6012521?

Yes, in 20 mm leather. On a 42 mm chronograph I like box calf: it holds its shape and carries a substantial case.

Which strap do you recommend for the Jaeger-LeCoultre Duomètre 6012521?

A 20 mm box calf. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
