Among the many material forms of Art Deco—from buildings to furniture to cars—clocks somehow seem to make the best use of the machine-age motifs that make the style so wonderful. Feverish geometric forms, mind-bending symmetry, high-contrast colors, modern and ancient materials combined with ticking mechanics and streamlined electricity in order to measure something more imaginary: time. Here are 18 clocks of that era that we just adore.
