What I'm asked about the Montblanc Star 102135
What strap size does the Montblanc Star 102135 take?
The Montblanc Star 102135 needs 22 mm between the lugs, usually 18 or 20 mm at the buckle. It's the size I've been fitting on it for years.
Can the strap on the Montblanc Star 102135 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 102135?
Yes, in 22 mm leather. On a 42 mm chronograph I like box calf: it holds its shape and carries a substantial case.
Which strap do you recommend for the Montblanc Star 102135?
A 22 mm box calf. You'll find it ready in the 22 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
