WASHINGTON, DC (WUSA) -- The comic strip character Dick Tracy used one. 

Now three companies hope you will wrap a smart watch around your wrist.

The time pieces link wirelessly with a smartphone or tablet.

The devices allow you to make or receive calls and link with health apps to help you keep track of workouts.

Experts estimate the wearable electronics will be a $10 billion industry by 2016.
