Top comment
Hey everyone, maker here. I got into mechanical watches a couple of years ago and pretty quickly realized how much of a black box they are. You wind it up, put it on, and just hope it keeps decent time. If you actually want to know how accurate it is, you either set it against a reference and check back in a week, or you drop a few hundred bucks on a dedicated timegrapher. I kept thinking my iPhone mic should be good enough to pick up the tick. Turns out it is, you just need the right DSP to pull a clean signal out of all the background noise. So I built it. Oscillo listens to your watch and tells you the rate, beat error, and amplitude in about 30 seconds. You can log readings per watch and see how each one drifts over time, spot when a service is due, and keep a record of every watch in your collection. Started as a weekend hack to scratch my own itch and slowly turned into the app I now use every time I pick up a new watch. Happy to answer anything, especially about the audio side. That part took a while.
