I'm the original owner. I'm guessing it's from the early 1970's. There is a significant crack on the plastic at around the 10, that is visible in the photo (which really adds to its vintageness).As of this writing it is ticking away and keeping good time. No fan of Mickey should be without it. It's about 2 inches in diameter. Good Luck with the bidding I hope it goes to a good home as it has left me with some very fond memories.
