Thanks! I found this post useful. I had a rep less than a year old gaining 37 seconds a day. I downloaded a timeographer app for my android and adjusted as posted. It is now running +/- 1 second a day! It was easy thanks to the directions and photos.
At the time of the posting I don't think a timeographer app was available for download. Now it is and it works well. It uses the microphone of your phone to check out your watch. Just hold the microphone against the watch and wait for the results.
