This authentic Cartier Santos 100 XL watch strap is made from black canvas with a black calf leather underside. It was originally removed from a Cartier watch with model number 2656 and will fit all watches with that model number. It will also fit other Cartier Santos models including 2774.
This strap is in very good condition and I have given you clear images of the strap from multiple angles to help you see the quality before ordering. The strap in the photos is the exact strap you will receive.
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!
