HP Calculator Heritage HP 01 - 1977

The HP-01, code-named ‘Cricket,’ is a digital electronic wristwatch, a personal calculator, an alarm clock, a stopwatch, a timer, and a 200-year calendar, and its functions can interact to produce previously unavailable results. But the HP-01 was not a successful product for HP. It was too bulky and heavy, and HP sold it though upscale jewelry stores. But miniaturizing the math functions was quite an engineering feat, and when HP discontinued manufacturing the HP-01, its inner workings were destroyed so no one would copy the extraordinarily small package engineering.
