Meet the Binary Watch: a geeky wearable with a low power micro controller to display the date and time. It has a bare PCB design and a ribbon cable that you can cut to make a custom length clasp. Since all the components are exposed with no housing, you should probably not wear this watch outside. It is available for $35.
