• Fully functional mechanical wall clock.
• 320 precise parts, no glue required.
• Gravity drive and moving balloon.

Build your own fully functional wall clock and master time with pure mechanics. Turning a plywood sheet into a working clock mechanism takes patience, but the result will blow your mind. Every gear and pendulum works without batteries and without a drop of glue.

Your reward for hours of careful assembly is a fascinating view of exposed gears in motion. A gravity drive powers the clock's precise movement, while a hot air balloon model slowly rises and falls every hour. You can even fine-tune the timing by adjusting the weight on the pendulum.

This detailed construction made from sustainable wood will test your modeling skills and become a striking centerpiece in any study or room. Start building and enjoy the joy of honest engineering craftsmanship.
