History of LED calculator watches
Watchismo, a stupendous vintage watch blog, has a drool-inducing feature on the history of calculator watches. (I would have blogged this post about the amazing, domed Rolex diving watch, but at $250,000 a throw, they’re more heartbreaking than wonderful.)
Playboy magazine, June 1975…A gift-giving
advertisement with ideas for dads & grads included this guy hidden
in the back. The Calcron LED Wrist Calculator. Likely the first public
offering of it’s kind.
