What I'm asked about the Cartier Ballon Bleu 40MM-WJBB0056

What strap size does the Cartier Ballon Bleu 40MM-WJBB0056 take?

The Cartier Ballon Bleu 40MM-WJBB0056 needs 12 mm between the lugs. It's the size I've been fitting on it for years.

Can the strap on the Cartier Ballon Bleu 40MM-WJBB0056 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 Cartier Ballon Bleu 40MM-WJBB0056?

Yes, in 12 mm leather. On a dress watch alligator is the natural choice: thin, elegant, what it was born for.

Which strap do you recommend for the Cartier Ballon Bleu 40MM-WJBB0056?

A thin 12 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.
