For your consideration is this nice little Bates & Bacon pendant watch case with an Illinois watch dial.
The case is marked 6/0 and the dial appears to be this size also.
The crystal is good with no cracks or deep scratches noted.
The dial has crisp, clear markings and is in good condition.
The case has some scratches and such, as well as a small dent at the back.
Please see the photos for more detail.
