Mechanical Clock Bubble Level A small bubble level to help put a mechanical clock into beat or just level it for an even tick tock. If the clock is showing that it is level, but the tick and the tock are not even, please read 'how to put a clock in beat' in the help sections. No clock will run if it is not in beat. However, this does not have anything to do with the clock being level. Although that is always optimal when putting the clock in beat. That way the next person to move it from here to there will still have it in beat providing that they also move it to another level place.
