I have seen many posts of late that are in regard to timing and accuracy. I am posting this (as a sticky) as a good reference for all to test and verify the accuracy of the watch. this will help you to determine performance, and whether to send back for regulation. As always, I recommend if any problems to contact Ball Customer Service.
Here are the steps to test/determine accuracy issues (below courtesy of Obie)
1. Never use a computer CPU to time your watch. Go to www.time.gov and set your watch from there.
2. Make sure the watch is wound fully when testing it, by winding it up before you set the time.
3. How active are you? Just wearing a watch 24/7 does not necessarily mean that you are active enough to keep it fully wound above its minimum power reserve. Many people have desk jobs where they don't move around too much.
To test it:
Wind it every morning 30-40 winds. Check it daily against time.gov at the same time per day. Do this for a few weeks to see what type of accuracy it is keeping.
Also if it is new, the movement could take several weeks to settle down into its normal accuracy. If used, do you know if the watch was opened, if it took any hard knocks?
Go that route and see where you are are. You may be surprised that you aren't active enough and that your computer CPU keeps horrible time. If your watch is still out 30 seconds per day, it may be covered under warranty. That said any local watchmaker should be able to get it within COSC spec with only a few minutes on their bench.
