What I'm asked about the Cartier Rotonde de Cartier W1556368
What strap size does the Cartier Rotonde de Cartier W1556368 take?
The Cartier Rotonde de Cartier W1556368 needs 23 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Cartier Rotonde de Cartier W1556368 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 Rotonde de Cartier W1556368?
Yes, in 23 mm leather. On a 42 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Cartier Rotonde de Cartier W1556368?
A 23 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.
