This is a strap that came with a Cartier TANK watch. I received it from someone, so I don't know if the strap is genuine. I used it frequently, so there are scratches and signs of wear. I'm selling it because I replaced it with another strap. The buckle is from the new strap and is new, but it's not Cartier. Size: Lug width: 15mm, Buckle width: 14mm. Length: 100mm, 75mm. Please note that these measurements are approximate.
