Design submitted by Daniyar from Kyrgyzstan.
Daniyar says: At first, there was an idea to make something like planets, rotating around the sun. But then i decided to place “planets” at the same orbit.External ring shows hour or month. Middle ring shows tens of minutes or days. And central dot shows minutes or days in numbers from 1 to 9. So, to find out how many minutes, you need to add the numbers that are indicated by the middle ring and central dot.
I think fans of minimalism might like this design.
