The Copal Caslon 401 is an iconic Japanese flip clock designed in 1964 by renowned Japanese designer Riki Watanabe and produced by Copal, a manufacturer internationally recognized for its precision electromechanical clocks. The model takes its name from the Caslon typeface, used for the numeric flip cards—an intentional and refined typographic choice that transforms the clock into both a functional timepiece and a design object of lasting cultural significance. During the 1960s, Copal was at the forefront of flip clock innovation, supplying both domestic and professional markets worldwide. The Caslon 401 was conceived as a wall clock, designed for modern interiors, architectural studios, offices, and cultural spaces where clarity, rhythm, and visual balance were essential. The historical and design importance of this model is confirmed by its presence in the collection of the M+ Museum in Hong Kong, one of the leading international museums dedicated to design, architecture, and visual culture. Compact rectangular case with softly rounded edges Elegant grey finish, understated and timeless Wide cream-coloured inner bezel enhancing contrast and readability Real glass front (not plastic), a rare and desirable feature Caslon-style black numerals on light-coloured flip cards Side-mounted adjustment knob, minimal and functional The overall design is perfectly balanced and expressive without excess, embodying the principles of Japanese modernism.
