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-WGBB0050?
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.
