Seeking info on inherited VC watch

I have inherited from family a Vacheron & Constantin Geneve Man's Watch with Gold weave band and would like to learn more about it and its maker.
There are three hallmarks on the back of the watch with also a set of numbers ??538109.  Front of clasp has the Swiss cross, back of clasp hallmarked with SWISS MADE, 750, Swiss Cross, three additional hallmarks.  Watch is in excellent working order.  Thank you for any information on how to learn more about this beautiful watch.
