Hey guys,   I bought a submariner from reg and it looks and feels great. It looses about 2 mins per day though. I bought one of these rubber ball case openers and tried to adjust the 21j movement myself. I didn't find a ton of guidance online so I wanted to ask you for some advice.   There is two levers, one with one dot and the the second with two dots. I moved both levers slightly to the left. Now I think my watch is quite a bit too fast. It has only been half an hour but it seems to have gained already some seconds. Can really only tell after a day I guess. Should I have left the lever with one dot alone and only more the two dot lever? What's the difference between the two? Thanks for any help!
