What I'm asked about the Jaeger-LeCoultre Duomètre Q604848J

What strap size does the Jaeger-LeCoultre Duomètre Q604848J take?

The Jaeger-LeCoultre Duomètre Q604848J needs 21 mm between the lugs, usually 18 mm at the buckle. It's the size I've been fitting on it for years.

Can the strap on the Jaeger-LeCoultre Duomètre Q604848J 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 Q604848J?

Yes, in 21 mm leather. On a 43 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Jaeger-LeCoultre Duomètre Q604848J?

A 21 mm calf strap, for every day. You'll find it ready in the 21 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
