The Rubik's Clock is a mechanical (not twisty) puzzle that was invented by Christopher C. Wiggs and Christopher J.Taylor. This is a two sided puzzle. Each side has 9 clocks, and on the sides there are 4 wheels, allowing each clock to be moved. I do not know much about the Rubik's Clock (because I don't have one), but the link that I leave below will give you more info as well as a solution to the puzzle.
