What I'm asked about the Bell & Ross BR-03 BR0392-AVIA-CA
What strap size does the Bell & Ross BR-03 BR0392-AVIA-CA take?
The Bell & Ross BR-03 BR0392-AVIA-CA needs 20 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 Bell & Ross BR-03 BR0392-AVIA-CA 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 Bell & Ross BR-03 BR0392-AVIA-CA?
Yes, in 20 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 Bell & Ross BR-03 BR0392-AVIA-CA?
A 20 mm calf strap, for every day. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
