Great app
Fun and easy way to track the accuracy of your watches. Not as accurate as using timegrapher but then we are talking about mechanical watches here anyways.

Twelve O’clock is an app that helps track your watch accuracy easily in a realistic way.
I can’t stress this enough: it’s “tracking”, not measuring instantaneous accuracy like a timegrapher device.
It’s a manual and oldschool job but it brings so much fun. It reminds me of the old days when I had to synchronize my watch to the clock on the TV at 7pm every day.
With Twelve O'clock you can:
** MANAGE YOUR WATCH COLLECTION
* Add, edit, remove any item in a list of your watch collection
* Include a nice wristshot of each watch
** KNOW YOUR WATCH ACCURACY
* Simply add some checkpoints and let the app calculate the accuracy in *second per day*
* A nice chart of the accuracy over the time
** LEARN MORE ABOUT HOROLOGY
* Curated content for watch lovers (like me)
