Not nearly that old and it was fairly inexpensive but I bought an Elgin pocket watch in 1966. It cost $38 and was no longer made in the U.S..
It was Swiss and 17 jewels. It still works fine and I suspect will keep doing so for a long time.
Oh yes, it took me a year or more to adjust just right but it kept near perfect time for a long time. I suspect it still would but I no longer use it and just wind it every years or so.
A jeweler told me it should be cleaned but he wanted more to clean it than I originally paid for the watch.
One thing to remember about the cost of purchase related to the cost of repair.
What was the cost of a gallon of regular in 1969 compared to today? How about a house then and one now?
Pretty soon we will all be millionaires and a hamburger with mustard/onions and a coke will be $9750.00 PLUS tax.
It is all relative.
I picked a ladies up for the wife on eBay back in 2009 as a Christmas gift. 1889 and the 14k case has “Charles to Rosie, Christmas 1889” calligraphied in it.
I got myself what I thought was an 1881/2 Hampton Duber on there around the same time. I was initially pissed when I got it because the guy had ended up listing the case # (irrelevant to age) rather than the movement # but the watch turned out to be a 1906 railroad grade with something like 27 jewels and was worth about 10X what I paid. That one will run about 36 hours on a wind and doesn’t lose a second.
