What I'm asked about the IWC Vintage Collection IW5445-04
What strap size does the IWC Vintage Collection IW5445-04 take?
The IWC Vintage Collection IW5445-04 needs 18 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 IWC Vintage Collection IW5445-04 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 IW5445-04?
Yes, in 18 mm leather. On a 44 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the IWC Vintage Collection IW5445-04?
A 18 mm calf strap, for every day. You'll find it ready in the 18 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
