As heard on our Pocket Calculator Show, this Seiko (also known as the “Voice Note”) was produced in relatively small numbers in 1983. The sound quality was poor, but this novel concept’s day would come in the form of a Casio voice watch some 15 years later. More interestingly, Dudley from Diff’rent Strokes wore this on a few episodes. Evidently, it was the only thing Mr. Horton didn’t ask Dudley to take off.
