Title: This smart-watch came out 38 years before the Apple watch Written by: duddy on Nov 14, 2015 (https://biology-forums.com/gallery/47/6_14_11_15_2_20_59.jpeg) (https://biology-forums.com/index.php?action=gallery;sa=view;id=22765) The 1977 HP-01 digital calculator was arguably the very first smart-watch to hit the market nearly 38 years before the Apple Watch. The watch was a marvel for its time. Not only could it perform basic calculations, the watch could do dynamic time and date calculations, algebra, and even function as a stopwatch and alarm clock. The watch in perfect condition can be found on eBay from time-to-time, for a price ranging up to $14 500 on eBay. |
