You're looking at an AUTHENTIC Officine Panerai 27mm/22mm alligator nubuck watch strap in XLsize.
I would be willing to sell this straight out, or trade it for the standard version of this strap, or a standard gold alligator strap.
Please do note this is the larger strap and will fit a larger size wrist. For tang buckle.
The item is in really good condition. This strap came with my Panerai 424 47mm Radiomir, but I just really haven't used it much at all, so I am putting this up for sale. Also note I am pretty certain that the watch is the model described, but please do cross reference. It is alligator nubuck, but I may have gotten the model name wrong. Feel free to let me know and I will edit the listing.
Price SOLD Shipped CONUS (will ship Worldwide for an additional fee).
I'm happy to answer any questions that you have. I have plenty of references available on WUS and other forums and on IG at briandicola.
