V1.3 - 04.11.2019:
Some explanation how it works:
Hours "spiral pointer": The spiral crosses the numbers on the clock face. This gives you information about the current hour.
Minutes "normal pointer": The minute pointer works like an average clock. But there are no numbers for the minute pointer printed on the clock face.
See below an example how to read the clock.

V1.4 - 05.11.2019:

In this version the minute counter is also a spiral and the clock face contains numbers for both pointers.
