What I'm asked about the Jaeger-LeCoultre Master Ultra Thin Q1313581

What strap size does the Jaeger-LeCoultre Master Ultra Thin Q1313581 take?

The Jaeger-LeCoultre Master Ultra Thin Q1313581 needs 18 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 Master Ultra Thin Q1313581 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 Master Ultra Thin Q1313581?

Yes, in 18 mm leather. On a 41 mm dress watch alligator is the natural choice: thin, elegant, what it was born for.

Which strap do you recommend for the Jaeger-LeCoultre Master Ultra Thin Q1313581?

A thin 18 mm alligator. You'll find it ready in the 18 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
