A watch that doesn't tell time?

I was listening to Wait wait don't tell me on NPR, and apparently this watch company came out with a new watch that sold out in 48 hours, but the watch doesn't even tell time. It tells you whether it is day or night.... I can't even begin to comment on how ridiculous this is, so just check it out http://blogs.wsj.com/wealth/2008/04/25/the-300000-watch-that-doesnt-tell-time/

Hope everyone is doing well with finals, it feels weird to be done!
