Mechanical Wooden Pendulum Clock
This beautiful mechanical wooden clock is a DIY kit, which means you should only go with this one if you’re up for a challenge. It does have clear instructions but requires a few simple hand tools to assemble including a small saw, some wood glue and sandpaper. It is mechanically powered, no batteries here, so you’ll also need to wind it periodically. But it’s a fun puzzle and certainly a very unusual clock.
