Wooden shops Wall Clock with Pendulum, 3D Mechanical Model Self-Assembling

Product Name: Wooden shops Wall Clock with Pendulum, 3D Mechanical Model Self-Assembling
A wooden clock is an actual working clock, wind up and watch the seconds, minutes and hours pass by.A clever 3D puzzle and DIY clock mechanism powered by gravity pulling down a weighted bag. As the weight slowly drops, it spins the drive gear, which then spins the escape wheel through the reducer.
