It’s been a long time coming, but someone’s finally resurrected the scientific calculator wristwatch. Billed as “the ultimate nerd status symbol,” the µWatch is made of off-the-shelf parts and contains 18 keys and a 16×2 line LCD screen.
Apparently the scientific calculator watch phenomenon has been dormant for about 20 years, as the Casio CFX-400 was the last of its kind sold back around 1987. The calculator watches you can buy today “are simple 4 function calculators” according to µWatch inventor David L. Jones.
There are links on Jones’ site for design plans and what appears to be an upcoming online store, but neither are active yet so you’ll have to try to build one based on the available photos for the time being.
