What I'm asked about the Breguet Classique 5717PT/AS/9ZU
What strap size does the Breguet Classique 5717PT/AS/9ZU take?
The Breguet Classique 5717PT/AS/9ZU needs 22 mm between the lugs, usually 18 or 20 mm at the buckle. It's the size I've been fitting on it for years.
Can the strap on the Breguet Classique 5717PT/AS/9ZU 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 Breguet Classique 5717PT/AS/9ZU?
Yes, in 22 mm leather. On a 43 mm dress watch alligator is the natural choice: thin, elegant, what it was born for.
Which strap do you recommend for the Breguet Classique 5717PT/AS/9ZU?
A thin 22 mm alligator. You'll find it ready in the 22 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
