It belonged to my maternal great-grandfather, William DOMELLE, b. 1882, d. 1943.
It came into my possession when I offered to have it cleaned for my grandfather. When I brought it back to him, he told me I could keep it. When wound, the watch keeps time quite well, but not for long. The ticking is somewhat soothing in this age of digital clocks. :-)
The manufacturer on the face of the watch is "Elgin". When I looked this up I found that there was an Elgin National Watch Company that produced mid-range pocket watches from 1874 to the early 1960s. Prior to that, they were named the National Watch Company. This watch company was based just north of Chicago. It just so happens that my great-grandfather spent a few years living in Chicago before he moved just south to the north-west corner of Indiana. I know for sure my great-grandfather was in Chicago between 1911 and 1913. By 1915 he was in Indiana. Any time in there could be when he bought this watch.
I did an image search online to see if I could find this exact watch, and I found many that had the same face, but different case, or similar case, but different winding mechanism at the top. Apparently, if I have the watch taken apart and the serial number on the movement noted down, I can then pinpoint when it was manufactured, so that will have to be on my list of things to do!
