The Graetz Form 99C (1975) and Form 100 (1976) clock radios
with a wild design destined to become a classic.
The first release was the Form 99 introduced in 1974 and had a flip clock.
They were offered with red or white plastic cabinets.
This Form 99C example was found with the cabinet nicely finished in lemon yellow.
The later Form 100 had a digital clock and the cabinet is a red styrene plastic.
