The Nooka ZAZ Watch allows you to tell time by lining up bars and blocks of liquid crystal over your skin. When it is dark, there is also a light which will illuminate time for you. Now you can make all those lame jokes about it being a ‘quarter after a hair’ while wearing your watch, although I suggest not doing so.

Available for around $400, you can check out more on the The Nooka ZAZ Watch by clicking the links below.
