A few months ago I wanted to buy an Hamilton Khaki Field and I found one on Ebay. But it noticed that it looked different than the standard model, and with some digging, I found many differences with the movement compared to the original ETA 2824-2. So I show you the steps I took to pretty much confirm that it is a replica and it can help you do the same.
