Vito Noto’s design for Pierre Junod’s Day/Night watch is a successful blend of rationality and poetry in which he advocates the return to a more natural reading of time, over a 24-hour period, and harmoniously evokes the opposition of day and night. The discreet case highlights the originality of the dial. A “sun” indicates the time by turning under the dial’s 24 numerals; the minutes are represented by a fine red arrow. The dial is light from 6 in the morning to 6 in the evening, and dark from 7 in the evening to 5 in the morning.
