This is a genuine Patek Philippe strap, imported and sold through authorized channels. It is a used item. It is a defective item. The front has some bending and edge scratches. The back has discoloration, and there are signs of use in two of the holes. The reason it's defective is that one of the loops for the strap is missing. The fixed keeper is not attached. The floating keeper is attached, so it can of course be used. Therefore, I am selling it at a low price, so please consider it(^^) A new one costs over 35,000 yen (゜∀゜) The size is 12mm at the watch side and 11mm at the buckle side. Please purchase after confirming the images.
