Here two alarm clocks for the blind of the company Junghans are presented. The open dial was designed so that people with visual impairment can feel the hands and the dial. Also on the back of a corresponding disc for setting of the hands with raised points for palpating is available.
The two alarm clocks were only a short time with me, I could only take pictures of them. Whether the paper-box actually belongs to one of the alarm clock is unlikely, even the clockwork was hidden from me. The hands are only present in fragments.
