What I'm asked about the Cartier Santos-Dumont WSSA0023
What strap size does the Cartier Santos-Dumont WSSA0023 take?
The Cartier Santos-Dumont WSSA0023 needs 15 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Cartier Santos-Dumont WSSA0023 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 Santos-Dumont WSSA0023?
Yes, in 15 mm leather. On a case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Cartier Santos-Dumont WSSA0023?
A 15 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.
