Imaginary Gear Mechanism Pendant

Description

This titanium pendant has a working gear train. Although they don’t look like it, the blobs on the face of the pendant are working gears, called imaginary gears, which have continuously varying gear profiles. They are powered by normal spur gears on the back, so they rotate when the gear on the right is rotated. It is a very strange thing to watch. We have the option to laser engrave the backside with a name or short inscription, although the gears back there will mean the inscription would have to be small. It’s a great gift for the gearhead in your life.
