I built one of these as my first clock and it was horrendous. It's almost impossible to set the time with a magnet without overshooting. I found it was better to split the hours and minutes, because otherwise if you overshoot the minutes setting it clocks the hours on.
I also found the CMOS very sensitive to stray noise and would often find the time had changed spontaneously.
