This is an authentic IWC brown alligator leather watch strap that was removed from an IWC Portofino model. It will fit other IWC watches that accept a 21mm wide strap.
I have given you clear images of this watch strap from every angle. The strap in the photos is the exact one you will receive
If you are not sure if this will fit your watch or if you have any other questions, feel free to email me at Sales@TheWatchLink.co.uk. I'm happy to help!
