Young London designers Grant Baker and NickJackson came up with, to discern the time on which not everyone can do it. The watch with the telling name "The Watch That I Can't See" is created according to the principle of a color test for color blindness - the dial is dotted with many circles of different colors and sizes. In four places of the dial, the numbers 12, 3, 6 and 9 are again folded from circles, dividing the clock into sectors familiar to the eye. But it is extremely difficult to see these numbers - glancing at the watch, as is usually the case, is extremely difficult to immediately see where the arrow is pointing. And for that small percentage of people who have their own color perception, popularly called color blindness, it will not be at all possible to find out what time it is.
