What I'm asked about the Montblanc Boheme 111209
What strap size does the Montblanc Boheme 111209 take?
The Montblanc Boheme 111209 needs 12 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Montblanc Boheme 111209 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 Boheme 111209?
Yes, in 12 mm leather. On a 27 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Montblanc Boheme 111209?
A 12 mm calf strap, for every day. 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.
