There’s not much to say about this clock except ‘wow!’. And possibly ‘where on earth do I get one?!’ Well, unfortunately for you, it’s a DIY clock made by some clever German in his basement, in the spare minutes between Star Trek reruns, probably.
The ‘Harddisc-Uhr’, as it’s known, features a rotating platter which allows for the time to be changed, instead of being a simple non-functioning stylish plate like most clocks. The reading arm moves left and right to indicate the minutes, and the hours are shown through the spinning platter.
