What I'm asked about the IWC Vintage Collection IW5448-01
What strap size does the IWC Vintage Collection IW5448-01 take?
The IWC Vintage Collection IW5448-01 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 IW5448-01 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 Vintage Collection IW5448-01?
Yes, in 22 mm leather. On a 46 mm dress watch alligator is the natural choice: thin, elegant, what it was born for.
Which strap do you recommend for the IWC Vintage Collection IW5448-01?
A thin 22 mm alligator. You'll find it ready in the 22 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
