Possible, but not worth it. You'll need to get new hands, datewheel, the dials feet will have to be cut, etc. As you see you're better off selling it and buying a better one.
My 2813 in my Rolex sub I have right now is not keeping time wel (-16min/day. I would rather put a high beat movement in it while I am at it. What is the best an easiest solution you suggest without buying a whole new watch? Getting new hands and so is no problem. Looking for getting into watch modding so a little bit of work is no problem.
