When he was told: "Only one!", he was completely dumbfounded and incredulous and said: "That is impossible! So many and so different operations and only one driving force? No, no, that's not possible, it's impossible!"

He thought that each dial must have it's own drive, which would mean that the tower would have to be stuffed with all kinds of different clocks. When it was explained to him, however, that there was only one drive mechanism moving all the hands, he was completely upset, because he thought that they were only joking with him because of his ignorance, and he went away and did not inquire further about this movement.
