Just inherited this, please help!

I just inherited this beautiful watch, however, I'm not really sure what I have.  It seems to be a mint condtion Vacheron Constantin, any ideas on the model/vintage? I would also welcome any reccomendations on how to go about selling this watch and what you think the value may be . Thanks in advance.
