I purchased this at Takashimaya Cartier, so it is undoubtedly authentic. I am selling it because I no longer have the opportunity to use it. I have not had it overhauled in recent years, so please arrange for maintenance yourself. The watch is running. The accessories have never been used. The leather strap has also never been used because the size doesn't fit. I have added a few extra links, so I think those with larger wrists can wear it. I measured the inside circumference of the watch, and it was about 19cm. Please forgive any slight measurement errors. Please check the photos for other detailed designs and conditions. I am very sorry, but due to the prevention of product substitution, returns are not accepted.
