keeps the brother entertained., 20 Oct. 2013

I gave this as a present for my mathematical genius of a brother for his birthday and he loves it, its big and much more interesting than a normal clock.

the clock doesn't come with glass to separate the hands of the clock from you touching them, this was probably removed since the last clock i ordered from the company which was a backwards clock , the hands kept hitting the glass, no matter how many times you opened it up and separated the hands. i have heard not all the equations on the clock are correct but anyway nice clock !
