What I'm asked about the IWC Da Vinci IW3766-01
What strap size does the IWC Da Vinci IW3766-01 take?
The IWC Da Vinci IW3766-01 needs 24 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the IWC Da Vinci IW3766-01 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 IWC Da Vinci IW3766-01?
Yes, in 24 mm leather. On a 44 mm chronograph I like box calf: it holds its shape and carries a substantial case.
Which strap do you recommend for the IWC Da Vinci IW3766-01?
A 24 mm box calf. You'll find it ready in the 24 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
