It’s been a long time since I’ve seen a scientific calculator wristwatch. They haven’t been around for about 20 years or so. Dave Jones remembers them well: “Back in 1987 or so I got a Casio CFX-400 scientific calculator watch, and I wore that watch to death for 10 years until the band support on the case broke. The CFX-400 was the best, and last scientific calculator watch ever sold.”

So if you’re like Dave, and has missed the calculator watch, there’s good news. He’s revived the scientific calculator wristwatch as a DIY project. His uWatch features a roomy LCD that can display 16 characters across, two lines deep, and it can handle all your fancy RPN/Algebraic scientific needs. You’ll need at least a bit of technical know-how to pull it off, but in the end you’ll have an awesome geek wristwatch that’ll catch the eye of lady nerds.
