Anyone Familiar With This Watch?

Hi, I own a Vacheron Constantin it was my father's and he gave it to me before he passed over 20 years ago. Its been in the case for years. It has the original certificate and maroon leather case. It was purchased in Switzerland in 1968. It is 18K Yellow Gold Extra-thin with Solid Gold Dial. The model is C16506, Movement 600555. Purchased February 26, 1968. Would anyone have any information on this watch. Thank You
