What I'm asked about the IWC Portugieser IW5000-03

What strap size does the IWC Portugieser IW5000-03 take?

The IWC Portugieser IW5000-03 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 Portugieser IW5000-03 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 Portugieser IW5000-03?

Yes, in 18 mm leather. On a 42 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the IWC Portugieser IW5000-03?

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.
