Rhythm Alarm Clock – Model 51102 Japan, late 1960s – early 1970s This original Rhythm alarm clock, model 51102, is a fine example of late-1960s / early-1970s Japanese Space Age design. The clock features a white plastic case with clean, sculptural lines and a distinctive brown sunburst dial, enriched by applied hour markers and luminous details.
