What I'm asked about the IWC Portofino IW3590-02

What strap size does the IWC Portofino IW3590-02 take?

The IWC Portofino IW3590-02 needs 20 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 Portofino IW3590-02 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 Portofino IW3590-02?

Yes, in 20 mm leather. On a 41 mm dress watch alligator is the natural choice: thin, elegant, what it was born for.

Which strap do you recommend for the IWC Portofino IW3590-02?

A thin 20 mm alligator. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
