You may have never ever seen a watch which doesn’t tell you the time. But 'The Memory Time Watch' is a unique concept from Wonjune Song that isn’t designed to exactly tell time. Song’s Memory Time Watch instead tells you how much day is left and how much has already passed.
The Memory Time Watch will start to black out portions of the face as the day goes by. The part that isn’t blacked out lets you know about how much time you have left before the day is done. Despite the fact that you can’t tell the exact time I really like this watch. I’d rather look at my watch and see that I have half a day left rather than 12 hours.
