Additional Information from a Watch Historian:


It sure looks to me to be an 18 size Elgin Model 1 movement. Elgin did many private labels, so I am not put off by the Ontario Watch Co. label.

There are, however, a couple of bothersome details like Montreal is not in Ontario! The other problem is that the serial number belongs to a 10 size Lady Elgin. If this is a Swiss Fake, it is a VERY good one. Usually there are signs that it is a Swiss fake, like oversize jewels or the balance cock jewel settings are screwed in from below. This REALLY looks like an 18s Elgin model 1.

Take a look at https://pocketwatchdatabase.com/search/result/elgin/6000 and compare. Look at the examples. The word “Patent” is in the right font and in the right place. It is even at the right angle. The damaskeening on the foot on the balance cock is right. Perhaps the Elgin records are wrong on the serial number. That happens from time to time.

Regardless, with a A solid silver case and a real or copy Elgin model 1 - I would date the watch to about 1870.

If it were mine, I would be taking it apart. I would look for serial numbers on the other parts. I would be looking for parts that do not belong in an 18 size Elgin Model 1. Perhaps a Swiss style mainspring. You can find details on parts including mainsprings here http://watchrepairinfo.com/1915ElginMaster.pdf

I am voting that it is a real Elgin, until an inspection inside shows otherwise. Still…..
