COPAL Caslon 401 This is a flip clock from the 1960s. The Caslon series was designed by Riki Watanabe's Q Designers office, and it has a very beautiful design for a digital wall clock of the time. I have checked the operation before listing it. This is one of the few 401 models with a black dial, and the original bluish-white fluorescent tubes beautifully illuminate the dial. *This clock is for 60HZ regions only. #FlipClock #MidCentury #RikiClock #RikiWatanabe #SpaceAge
