This is a genuine Cartier Tank Divan watch strap that was removed from a Tank Divan watch with model number 2602 but it will fit others. There is a small bit of leather peeling at one of the buckle holes but this is hard to see.

Your watch strap is 29mm wide where it connects to your watch and it is 22mm wide where it connects to your buckle. Your longer strap piece is 10.5cm long and your shorter strap piece is 7.5cm long.

I have given you photos of your watch strap 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.
