What I'm asked about the Bremont Supermarine 500M
What strap size does the Bremont Supermarine 500M take?
The Bremont Supermarine 500M needs 22 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Bremont Supermarine 500M 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 Supermarine 500M?
Yes, in 22 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 Supermarine 500M?
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.
