What do I own?

Hi! My wife's dad was American and he owned this Vacheron Constatin watch. We would highly appreciate to know what's the model, year it was made in and the value. At the back of the case we can read "julile". We don't know how to open the case and so presently we can not give you further info apart form what you can see from the attached pics. The number 750 can be read inside the bracelet closure. I'm terribly sorry for this very poor description... but my wife and I will highly appreciate your help.

Sorry, this was not meant to be a poll but a "help request" to identify this watch! I'm Italian and can't understand all the instructions given to mpost my msg properly!
you need to have the back opened and give us the numbers inscribed

as well as the movement number. Just from the photo the dial looks redone as the shape of the brand inscription is not correct

Finally I have the numbers: 484379 is the "movement number" and the other number is 316586. Hope they can be helpful to date this watch and have an idea of the value. Many thanks again for sharing your knowledge. Renato
