This is an authentic Cartier Tank Louis vintage brown alligator watch strap that was removed from a new watch.

Your watch strap is 17.5mm wide where it connects to your watch and is 16mm wide where it connects to your buckle. The longer part is 10cm long and the shorter part is 9.5cm long.

I have given you photos of your watch strap from every angle. Please use them to add to this description.
