What I'm asked about the Montblanc Star 102136
What strap size does the Montblanc Star 102136 take?
The Montblanc Star 102136 needs 20 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Montblanc Star 102136 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 Montblanc Star 102136?
Yes, in 20 mm leather. On a 40 mm dress watch alligator is the natural choice: thin, elegant, what it was born for.
Which strap do you recommend for the Montblanc Star 102136?
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.
