TimeFlex is a unique concept idea which uses a "self-gumming" sticker like watch which can stick on to any surface such as your hand, arm or clothing. The idea behind it is that sometimes you need a watch on you but it's not always a good time to do so, such as when swimming. This watch could literally be stuck to your wrist or swimwear and not create any drag.
It's not a concept I expect to see happen too soon though.
