This is a watch strap for Patek Philippe. A relative owned a watch store, but it closed down, and I received the remaining watch straps, so I am selling them. I don't know much about watches, so I may not be able to answer all questions, but I will try my best to assist. Thank you. I was told it is new and unused, but please check the photos. We will proceed with the transaction assuming you understand that there may be oversights. Please feel free to ask any questions. Thank you for your understanding.
