While travelling the world, you really get in touch with different time zones. The main idea was to create an analogue clock that enables you to read the time in different time zones. The human brain is able to read a clock from an early age, thus you do not need digits to recognise the time. With turning the complete clock, the hour hand is moving to the next time zone. Every 30 degrees the clock locks and it is one hour later. The city on the top of the clock is the updated time zone.
