Hello all   Like in title, I would like some advice on how to do this myself any help or link to videos on this type of watch would be very apreciated   Here is the best picture I could take, stem seems to have snap flush in crown   Is this fixable sorry for nasty pics this is was my sports watch so it got alot of abuse, the watch is still working, but obviously is useless if I cannot change time and date. thx in advance   Nick
