This is an American watch case opener.
These were given away as promotional gifts from the case makers and watchmakers of the time. Occasionally a private retailer would then engrave the business name on reverse and very occasionally the whole item was produced by an individual jewellers or watchmaker rather than a larger company.
These steel case openers are all designed to open pocket watch case although I would advise that you should have some experience before trying this with an older case opener such as these as a slip could scratch the case.
This example is from the Jas Boss / Keystone case makers and is in the shape of a pocket watch.
One side has details of the company with the details of their Non pull out bow ring
The reverse is engraved Watch Case opener presented by Keystone Watch Case Co, Phila
The opener can be attached to a watch chain
It measures 37mm x 25mm and is in 95% mint condition
