Vintage style crystal ball mechanical pocket watch desk clock. Very solid\/heavy magnifying crystal gives a really cool affect. Use this in your steampunk creations, take apart, or just use as a desk clock. It is in working condition and has in indent on the back so it sits nicely on your desk or mantle. I just love the back which shows the working gears magnified by the crystal glass. The diameter measures about 2 1\/2 inches.
