Build your own beautiful gravity clock, and customize it using your own counterweight! Mechanical gravity clocks ruled the Earth from about 1300 to 1927 when the quartz movement debuted. They needed no electricity -- just a weight tugged by gravity.
Easy to build -- instructions are in Japanese but feature highly detailed assembly pictures (sorry, no English translation at this time). MAKE is proud to be the exclusive distributor in North America for these brilliant kits from Gakken.
