Design submitted by Logan from the USA.
This watch design is Logan’s response to two challenges: 1) measure time not using hours and minutes and 2) develop more creative analog watches.
This watch concept displays the time only as hours, with up to three decimal digits of precision. For example, 09.750 = 9:45, 04.333 = 4.20, and 12.817 = 12:49. Even just reading the first decimal digit provides a quick approximation of the time, since 0.1 = 6 minutes (so 12.8xy = 12:8*6+ … = 12:48 + …). Major divisions of the hour, such as 0:30, 0:15, 0:20, etc are also easy to recognize or remember.
This is a purely analog watch, with the hours and three decimal digits painted onto four rotating rings. A rectangular hole in the steel case reveals the time.
This watch is for the mathematically inclined and for people who like to explore different ways of thinking about the world.
