Antique Hampdon Pocket Watch 1890's it works - $150 (indio near shadow hills high school)

Up for sale is a Antique Pocket Watch made by Hampdon Watch Co.
I bought this off ebay about 5 years ago from a collector, who in his listing said it was made around the late 1890's This is a "lever set" watch.
The glass looks to be in good shape, and has no chips or cracks.
The back has a couple of small dents, and some scratches from prior use.
It does work, but runs slow.
It should probably be serviced.
$150.
