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)
