vintage United electric pocket watch wall clock, metal w/ convex glass

Vintage United electric 'pocket watch' wall clock, runs fine (keeps good time, nice and quiet!). This one is about 7 1/2" in diameter with a cord to plug into a wall socket.

The case is metal, with a little wear and scratching to the gold colored (brass plated?) finish. The cover glass is glass, not plastic, clear and free of scratching.
