What I'm asked about the Jaeger-LeCoultre Master 1538171
What strap size does the Jaeger-LeCoultre Master 1538171 take?
The Jaeger-LeCoultre Master 1538171 needs 19 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Jaeger-LeCoultre Master 1538171 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 1538171?
Yes, in 19 mm leather. On a 40 mm chronograph I like box calf: it holds its shape and carries a substantial case.
Which strap do you recommend for the Jaeger-LeCoultre Master 1538171?
A 19 mm box calf. You'll find it ready in the 19 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
