Watch project for the blind

Hello all

I am designing a vibration controlled watch for blind people,
I was wondering which arduino kit would be best to use.

The watch uses four vibration motors in a 24 hr method.
The watch has four panels, on which seperate vibrations can be felt.
so if the time is 15:32
then the first panel gives one vibration, the second panel gives five vibrations ... and so on.

Thanks
