What I'm asked about the Bremont Altitude ALT39-DT-SS-SI-L-S
What strap size does the Bremont Altitude ALT39-DT-SS-SI-L-S take?
The Bremont Altitude ALT39-DT-SS-SI-L-S 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 Bremont Altitude ALT39-DT-SS-SI-L-S 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 Bremont Altitude ALT39-DT-SS-SI-L-S?
Yes, in 20 mm leather. On a case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Bremont Altitude ALT39-DT-SS-SI-L-S?
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.
