**This is a model clock kit run by a manual hand crank and not a real clock. For a functioning clock, check out the Owl Clock or the Zodiac Clock.
The Mechanical Series feature precise, laser-cut pieces that come together to form ingenious designs. Build a marble run that consists of a turn-crank, cogs, drops and spirals! You can also build a functioning record player, or even a miniature film projector.
We even have vehicle puzzles equipped with a spring motor that launches it forward up to 10 feet!
