The ready-to-wear strap is 115 × 75 mm. For a smaller or larger wrist I make it in the right length: order your length.
What I'm asked about the Jaeger-LeCoultre Master Ultra Thin Q1242502
What strap size does the Jaeger-LeCoultre Master Ultra Thin Q1242502 take?
The Jaeger-LeCoultre Master Ultra Thin Q1242502 needs 17 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Jaeger-LeCoultre Master Ultra Thin Q1242502 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 Q1242502?
Yes, in 17 mm leather. On a 36 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 Q1242502?
A thin 17 mm alligator. I don't keep this size ready in the catalogue: I make it to measure. If you'd rather have something built on your wrist, the Casati atelier.
