The lack of information in the manual about the position and function of the light sensor meant that I judged the clock as faulty and sent them back to Amazon. The replacement watch showed the same characteristics and I thought again that he had received a fehlterhafte clock. Only a callback when the manufacturing company brought clarification. The light sensor is integrated on the clock in the top left. By switching / masking the permanent display of the Projection clock can be achieved. Otherwise, I agree with all the positive reviews of previous reviewers in full.
