My father gave me a VC Quartz watch that he had for a very long time. The serial number is 559042. The buckle and the back of the case is marked 750 and both are hallmarked. On the face it says Vacheon Constantin Geneve. A cross above the name. The watch is also marked Quartz and Swiss along the bottom. The case is an Octagan in shape and very thin 1/8" in thickness. The band is black crocodile and is also marked VC. The face has a rose,yellow,and white gold strip pattern than runs from top right to bottom left. Any information would be useful. I would ask my father, but he pass away a couple of years ago. I thank you in advance.
