What I'm asked about the Breitling Colt A7438953.A771.239X

What strap size does the Breitling Colt A7438953.A771.239X take?

The Breitling Colt A7438953.A771.239X needs 18 mm between the lugs, usually 16 mm at the buckle. It's the size I've been fitting on it for years.

Can the strap on the Breitling Colt A7438953.A771.239X 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 Breitling Colt A7438953.A771.239X?

Yes, in 18 mm leather. On a 36 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Breitling Colt A7438953.A771.239X?

A 18 mm calf strap, for every day. You'll find it ready in the 18 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
