What does "Accuracy: +25 to -15 sec/day" for an automatic watch?

Update:

Does that mean the watch can gain 25 seconds a day and lose 15 second a day? Just confused how that works

    Yes, it is possible it will do one or the other of those things on any given day. It's not really very accurate, as watches go.
