What I'm asked about the Breguet Pilot 3815TI/HO/3ZU
What strap size does the Breguet Pilot 3815TI/HO/3ZU take?
The Breguet Pilot 3815TI/HO/3ZU 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 Pilot 3815TI/HO/3ZU 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 Pilot 3815TI/HO/3ZU?
Yes, in 22 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 Breguet Pilot 3815TI/HO/3ZU?
A 22 mm calf strap, for every day. You'll find it ready in the 22 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
