Nintendo retro clocks - Ultraman, Kamen Rider and others
Around the turn of the 1970s, there was a boom in super hero merchandise in Japan. Television had become a mainstream entertainment medium and there were many popular television shows around characters like Ultraman and Kamen Rider.
Toy manufacturers capitalized on this phenomenon and produced boatloads of games and other items with super hero imagery. Nintendo also acquired licenses to use the protagonists of a number of these television series and used these for things like board games, playing cards and N&B Block construction sets.
In 1971 Nintendo extended their product line with a series of super hero themed electric clocks, called E-clock. The Japanese name was simply Nintendo Electric Clock (任天堂 電気時計).
There are 4 different super hero clocks in this series: Mirror Man, Silver Kamen, Ultraman and Kamen Rider.
