This is an authentic TAG Heuer F1 ladies watch link that measures 12mm wide and it comes complete with the original pin needed to attach it into your watch strap. This will fit your watch strap if your clasp is stamped 495/3.
I have given you photos of your watch link from every angle. Please use them to add to this description.
If you are not sure if this will fit your watch or if you have any other questions then message me. I'm here to help you.
