I have been stalking this watch for over a year. I Love it.
It is actually modeled after an alligator, having something to do with an actress or opera singer who wanted something made by Cartier for her to resemble a little alligator or crocodile. They came up with the famous wrap around watch when you open the mouth the inside shows the watch face (yuck!)
Anyway this is a gorgeous piece - I am looking to get it in the yellow or rose gold no diamonds. I have a diamond watch in white gold already and don't want to do a repeat.
If you go to the Cartier web site, it also comes with the same face but with leather straps which creates and entirely new look.
What else are you considering? Roadster? Tanks?
