.....a beautiful and classy Calatrava.
To be honest, I am not sure about the box. I have not seen one like that before and have not bought watches in that era to verify. It may well be perfectly correct, but I am not sure. Will try to dig into it. Looking at other versions for sale, they have the box I am more familiar with, so it will require more digging but it is possible this is not the original box
Congratulations again on that superb watch
