My father passed away a few months ago. While going through his personal items I found a Vacheron watch, I don't remember much about the watch but it seems to me he bought it a number of years ago (15-20 years). Can anyone tell me about the model or other info? Value? The watch back has the numbers 653555 or 553555. The watch has no minute hand/ no date and the face is very light gold with a basket weave pattern. Leather strap. ???????? Thanks. I have contacted Vacheron but have not yet heard anything from them.
