Genuine Patek Philippe Brown Leather Strap for Nautilus 5712/R BRAND NEW

Brand new guaranteed authentic Patek Philippe brown leather strap. Original receipt for the watch is shown in the photos (it's not included in this auction as I need to keep it for my insurance records) - this was an extra band that was never used. I have the original box being sold in a separate auction but this is just for the leather band! From a smoke-free home!
