Replacement strap

I have a Portuguese, 7 day (5001/09, Black dial, 42mm) that I acquired a few years ago on vacation. It is a great daily wearer, but my strap is beginning to show its age.

I don't live near an AD, but would like to purchase an OEM strap. How do I go about buying one? Call the closest dealer?

Thanks in advance.

Hello and welcome! Yes, call your nearest authorized dealer. They most likely will be able to order it and have it sent to you and then you could have it switched out locally. IWC boutiques may already have the strap on hand, but any AD can get the strap for you.
