thank you for photo some questions: I don't touch the 2 knob, I think the clock run normally. When run normally, the white pointer of hour and minute turn - run . The orange pointer of seconds , always run concurrently with minute and hour ? or standing still? when the left knob is pushed ,the charachter plate run / rotate , and is stopped when repushed for 2° time ? The motor inside the clock, run with 12Volt , with 5 volt or other tension ? What is the shape of wave , for the motor ? example 5volt for 1 second ?
