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)
