What I'm asked about the Montblanc Star 107309
What strap size does the Montblanc Star 107309 take?
The Montblanc Star 107309 needs 19 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Montblanc Star 107309 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 107309?
Yes, in 19 mm leather. On a 39 mm dress watch alligator is the natural choice: thin, elegant, what it was born for.
Which strap do you recommend for the Montblanc Star 107309?
A thin 19 mm alligator. You'll find it ready in the 19 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
