When it comes to the world of wearable technology, two particular niches stand out from the rest of the crowd – one of them would be a smart watch, while the other would be a pair of smart glasses. The former has certainly made some interesting strides in the previous year and especially this year, but certainly the grand-daddy of them all should be noted – and we don’t suppose that HP is a frontrunner in this department. What you see above happens to be the HP-01, which is the first calculator watch in the world. Yes, it certainly looks very different from the svelte versions that Casio churned out in the later years, right?
For starters, the HP-01 happened to be huge, really huge. In fact, you can say that the chassis that came in a shade of gold is definitely able to be a firm favorite among rappers of today, and most of it is made out of stainless steel. The asking price for the HP-01 calculator watch prototype? Well, if you happen to have $14,500 sitting somewhere in your bank account, not to mention having to fully trust the eBay seller, then go ahead and own this piece of technological history.
