Young London designers Grant Baker and NickJackson came up with a watch that not everyone can see. The watch with the telling name "The Watch I Can't See" was created based on the principle of a color test for color blindness - the dial is dotted with many circles of different colors and sizes. In four places on the dial, the numbers 12, 3, 6 and 9 are made up of circles, dividing the hours into sectors familiar to the eye. But it is extremely difficult to see these numbers - just by glancing at the watch, as is usually the case, it 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 be completely impossible to know what time it is.Figures on the watchColor numbers
