100% Authentic Cartier tank 2303 quartz

Cartier tank solo watch, I love this wristwatch but is time to go. I do not have the original strap anymore, however still have the one of the original clasps/buckle. The watch was purchased in London, I have used 2 different straps since I got it & I so have another authentic strap purchased but never got to put it on it because it was bigger, I just didn't bother to return it. If I get a reasonable offer I will throw the strap in for free. It also has a crack, that actually happened recently
