This is a smaller sized open face pocket watch from Puritan, an Ingersoll company. It has a solid silver metal case, mineral crystal and a new stainless pocket watch chain. The fineness of the case isn't known but I'd wager at least coin grade, probably sterling.

It has some wear but is in excellent aesthetic condition as shown.

It's runs normally and keeps good time from my observations.

The crown winds smoothly. It's free moving but without excessive play or binding. The watch runs smoothly and softly without excessive noise  It will probably need serviced in the mid term to keep it running nicely (but what mechanical watch doesn't?) but as of now it runs just fine.
