Five minutes late

Hi,  I have an fairly inexpensive watch,. it loses about 5 minutes per week,,. I can access the adjustment + and -,. do I turn the slot towards the + or away from the +,. my father was a watch repairman,,. he died about thirty years ago, the things he told me as a kid went in one ear and out the other,. so I don't recall on the adjustment,. there is no harm to be done, as it's not a valuable watch,. I live in a small town with no watch service,. guess I'm just doing this out of curiosity and something to do,. thanks for any help,.   bob,....
