This is a new and authentic Cartier watch link bar made from solid 18ct gold, sealed in its original Cartier International Service packaging. It will fit Cartier Panthère 1120 watches and some Cartier Figaro ladies models. This is a genuine factory part and has not been opened.
There are photos of your Cartier watch part from multiple angles to help you see the item clearly.
If you are not sure if this will fit your watch or if you have any other questions, feel free to email me at Sales@TheWatchLink.co.uk. I'm happy to help!
