Another word you’ll run into soon is “Frankenwatch,” especially in the antiquarian world. The term describes a watch made from two (or more) other replica watches parts. As a result, a seller would be considered a Frankenwatch, if he replaced one with another with a broken dial.

Components will get replaced over the years because of wear and tear, and if the manufacturer replaces a damaged dial with a new one, that does not make the timepiece a Frankenwatch, as the new dial is intended for that exact model. Now, is a Frankenwatch always a bad thing? Not necessarily.
Apparently, as we learned above, originality is highly prized in vintage watch circles, and so a Frankenwatch will be looked down on somewhat by the true connoisseurs. However, if all you are after is just a good-looking vintage watch at a low price (and a model with mismatched parts will, or should, be pretty much cheaper than a totally original one) then they can be an attractive option.
The trouble starts if you happen to fall foul of a less than the seller. Those hawking Frankenwatches and claiming them to be all original (and charging accordingly) are a blight on the industry and there are some of them out there.
That’s why it’s so important to do your homework in the buying process. There are some real experts who give their advice on fake rolex watch forums. Taking a few minutes to consult with someone who has studied the details of various vintage watch brands for decades can save you a lot of money in the long run.
