It turns out there’s no reason to drop $20,000 on an expensive Swiss watch if you happen to have a box full of Technics lying about, because someone has built a working split-seconds chronograph using nothing but Lego.
A split-seconds chronograph functions like an analog stopwatch, except with an additional seconds hand that can be randomly stopped and used to time two events that start at the same moment. As far as watchmaking goes, it’s not the most complicated movement to build—unless you limit yourself to only using a plastic building toy; then it’s quite an accomplishment.
With enough pieces you could eventually build yourself a complete mechanical watch, as long as you’re not worried about accuracy, fitting it on your wrist, or how how well it would pair with a nice blazer. [YouTube via Hodinkee]
