I was looking at this Eberhard pre-Extra Fort listed on eBay. There appear to be some issues with the movement, but the watch is still interesting to me. However, I noticed that the numbers stamped on the back of the lug (hard to read, but ending in "92" I believe) do not match the last few numbers on the inside of the case-back (25040). I don't know about Eberhard specifically, but I think the lugs were often stamped as a way to indicate which back was paired with which case. Does anyone know if they are supposed to match?
