Why buy new?
I just bought a Elgin wind up pocket watch this morning at a local flea market for $30. I liked it, it ran, looked good, so I bought it. Felt good and sturdy. I love pocket watches for some reason, dunno why.
I get back home, and check the internet on this watch. Serial number 7022698. Turns out it was manufactured circa 1897. There was only 5000 produced in the series, manufactured from 1886 to 1898. In the year this was manufactured, I have one of 117 watches produced. The case is silver, 7 jewel movement, size 18s grade 73, and was intended for mainly general use and railroad use.
What is it worth? Dunno exactly, but it looks to be well over $250+ from what I can find. You buy a new watch, and 10 years later you throw it away.
