This carriage clock looks like an over sized open face pocket watch. It is 4" in diameter in white metal. I have not found any maker's mark on the dial or inside the works. The white enamel dial has a couple of spots of crazing or cracks, one near the number 7 and the other across the top between the numbers 10 and 1. The clock does not work right now, although the balance wheel rotates when the clock is gently shaken. The crown needs to be reconnected to the works, so that the time can be set, and a cleaning is probably in order. Accordingly, I am selling this novelty item As Is.
