Hi this is my first post on here. Two years ago my wife bought me a very nice bi metal datejust. It was fully refurbed and is in superb condition. The dealer i purchased the watch from said it was from 1968, but after looking up on some of the case number sites it looks as though it could be 1969. I have two questions. The first is what year is it? The case number is 2866036. The second question is what type of gold is it? The dealer thought it would probably be 14ct as this was used instead of 18ct around that time, is this correct? I would love to know the answers, so over to you gentlemen.
