My original smart watch design was really primitive, it relied solely on the micro-controller for timing meaning that when it turned off the time was lost.

My new approach follows the traditional method of electronic time keeping, using an RTC (real time clock). I have decided to use the DS1307 module since it operates at 5 volts. 

I will also be working on creating a menu and settings page so that the user can change the time more easily. 

Stay tuned!
