Design me a Product

A smart watch that can connect to any phone/tablet/pc through the custom app and can send msg, play music, store your important files, call phones, and even monitor your homes security system when your out and about. All from a 2inX2in HD screen and a voice recognition mic. I have not yet decided the material that the out side of the watch will be made of but it will come in a variety of colors after the prototypes have been built and tested. As for the electronics in hoping the person/s i hire will have some valuable ideas.
