The Chromachron by Tian Harlan is a design-focused watch that displays time through a rotating color scale rather than conventional hands and hour markers. The black dial emphasizes the circular spectrum, giving the watch a distinctly graphic and highly unconventional appearance. Designed by Tian Harlan, it reflects an approach to watchmaking centered less on traditional cues and more on visual interpretation, making it an interesting example of late-20th-century experimental wristwatch design.
