What I'm asked about the Jaeger-LeCoultre Reverso 381357J

What strap size does the Jaeger-LeCoultre Reverso 381357J take?

The Jaeger-LeCoultre Reverso 381357J 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 Reverso 381357J 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 Reverso 381357J?

Yes, in 20 mm leather. On a 27 mm dress watch alligator is the natural choice: thin, elegant, what it was born for.

Which strap do you recommend for the Jaeger-LeCoultre Reverso 381357J?

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.
