Hi guys, I been lent an old VC from a work contact to potentially feature on my channel. He's not much of a watch guy and can't tell me much about it at all. Any help with identifying this would be much appreciated!
Number on case back is: 640495. Otherwise it just says "Vacheron Constantin" and Geneve in the center.
Case diameter is 32mm, lug width 17mm, thickness 5.5mm (!).
