Knowledge is power.

I am always stupid enough to enter any contest that comes along. Timex watches had this contest to devise the watch of the future, and I entered one that eerily looks like a smartphone ear piece (this is 18 years before the iPhone). The prototype was made out of balsa wood and glue. To find out the time, you simply clench your jaw.

THE ORACLE.

This is the information age. Knowledge is power. And nothing is more powerful than knowing what others want to know. Now the secret of time is yours. To hear the time, gently squeeze down on your jaw (in a rhythmic sequence you program) and The Oracle, detect­ing this distinct pattern through micro sensors, silently whispers the time in your ear. It is up to you whether to share this knowledge with others.
