What I'm asked about the Wren Diver 38 diver 38 diver38 crimson date
What strap size does the Wren Diver 38 diver 38 diver38 crimson date take?
The Wren Diver 38 diver 38 diver38 crimson date 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 Wren Diver 38 diver 38 diver38 crimson date 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 Wren Diver 38 diver 38 diver38 crimson date?
Yes, in 20 mm leather, as long as you don't wear it in the water: leather doesn't like the sea or the pool. For days in the water, rubber.
Which strap do you recommend for the Wren Diver 38 diver 38 diver38 crimson date?
Rubber if you wear it in the water; otherwise a 20 mm calf strap, full thickness. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
