Design submitted by David from UK.
Looking for alternatives to the Twelve 5-9 format, David wanted a system that was simple to read if you know the code, but of course difficult if you don’t.
Time is read by reading the 4 rows from top to bottom, the first 2 are hours and the second 2 are minutes. You square vertical lines so I = 1, II = 4, III = 9. \ means -1 and / means +1. So, \\III should equal to 7 and II// equals to 6.
This watch design should appeal to people who like codes or math. It is a unique way of displaying the time and with practice it’s very easy.
