What I'm asked about the Jaeger-LeCoultre Geophysic 800652J

What strap size does the Jaeger-LeCoultre Geophysic 800652J take?

The Jaeger-LeCoultre Geophysic 800652J 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 Geophysic 800652J 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 Geophysic 800652J?

Yes, in 20 mm leather. On a 39 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Jaeger-LeCoultre Geophysic 800652J?

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