QiYi has finally perfected their first version of a clock puzzle! This clock is by far the highest quality option available which is quickly noticed when using the puzzle.

Featuring a total of 208 magnets (204 small, 4 large) the movement is very precise and all dials, buttons, and rings are equipped with magnets.

What's so great about this clock is that it will save clock enthusiasts from having to modify lower-end clocks which is not only time consuming but runs the risk of damaging components.
