Description of Twelve O'clock

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)

Reviews of Twelve O'clock

  • Easy way to track accuracy of my mechanical watches

    Twelve is simple to use and track the accuracy of your watches. It’s a great app and I hope that it continues to be supported.
  • Great app

    Simple interface, easy to use. Does exactly what it needs too. $0.99 for one time purchase of full version is well worth it!
  • Excellent app for tracking my Grand Seiko

    This is a great app for tracking the accuracy of your watch. The easy to understand interface allows you to mark the time on your watch at the hour mark or at the 15-, 30-, or 45-second mark so you don’t have to wait a whole minute if you miss the top of the dial.

    (My Grand Seiko GMT High Beat has been tracking at about +2 seconds per day.)
