What I'm asked about the Ball Watch Fireman CM3090C-L1J-WH
What strap size does the Ball Watch Fireman CM3090C-L1J-WH take?
The Ball Watch Fireman CM3090C-L1J-WH 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 Ball Watch Fireman CM3090C-L1J-WH 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 Ball Watch Fireman CM3090C-L1J-WH?
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 Ball Watch Fireman CM3090C-L1J-WH?
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.
