What I'm asked about the IWC Vintage Collection IW3233-07
What strap size does the IWC Vintage Collection IW3233-07 take?
The IWC Vintage Collection IW3233-07 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 IWC Vintage Collection IW3233-07 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 Vintage Collection IW3233-07?
Yes, in 22 mm leather. On a 43 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the IWC Vintage Collection IW3233-07?
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.
