Watch With Calculator Views
This style of watch has been around as long as many of us have. But that doesn't mean it's old or dated or useless. NAY! We say that it's just as useful today as it was back in 1975. Where did we find the first ad for a calculator watch? Playboy, of all places. (Seriously, we were there for the advertisements!) The CALCRON was ahead of its time with its solar power, LED screen, and ability to do math right on your wrist. It was soon followed by a calculator watch by an obscure company called Uranus. (We REALLY wish we were joking!)
Casio's Classic Calculator watch is a splash-resistant, multifunction watch with integrated calculator touchpad. It's sporty and casual, so it'll go with what we're pretty sure you're wearing right now. It has flexible stopwatch functions with 1/100th second increments and split time. Use it to set your daily alarm, or to beep every hour to remind you time is passing. The Casio Classic Calculator watch will display time in 12 or 24 hour modes, so you military or Euro-folks can have a familiar face. (Get it, face? Ugh, that was awful.) Most importantly, the auto calendar will work until the year 2079, when we will SURELY have our flying cars.
By 1975 the electronics required for a calculator had shrunk so much that it could be shoe-horned into a watch casing. The first was the Pulsar calculator watch, made by Time Computer Inc., of Lancaster, Pennsylvania, U.S.A., formerly the Hamilton Watch Company. This was followed over the next couple of years by models from Hewlett Packard (HP-01), Compuchron, and Uranus - all with LED displays. Sinclair produced an LED wrist calculator, but without the time function.LED calculator watches were marketed for only a few years before being replaced by LCD (Liquid Crystal Display) version, which have much lower power consumption and display the time continuously.The rate of development was so fast that LED watches and calculator watches were often left unsold, and are now sometimes available to collectors as new old stock (NOS).
