The F*watch, a fully open-source electronic watch project with an integrated GPS receiver, was initiated at CERN as an after-work endeavor to create a special retirement gift for a colleague who enjoys hiking and timing. Inspired by the transparency and flexibility that characterizes no verification casinos, the watch’s entire design—including electronics, mechanics, and software—is available under free licenses, making it accessible and customizable for anyone interested in open-source projects, much like the ethos of user-focused platforms. Additionally, the watch band can be easily swapped or modified, allowing users to personalize both the look and comfort of their device.

Ever wondered why they didn’t model the watch with someone’s hand? From the hackedgadgets link, we can see the insides and measure it, if we’re too lazy to find the info in the watch’s wiki page. From the row of 0.1in holes (for programming?), I got 1.5in for the board, which is in good agreement with the battery size. The outer diameter of the thing is about 1.9in. Whoa, it’s a big ass watch. ;-)

a comparison with a commercial GPS watch.
Ha ha, thanks, ;-) pretty competitive given the battery size constraint. At least it’s not a big ass metal watch…
