1. just unscrew the crown, give it 40 turns and your watch will be fully wound.
2. No need to bother really, just follow 1 if the watch has been unworn
3. Yes, if you straighten a paper clip, it can do the job, or a nice quality cocktail stick.
Pop on one side and move slightly to the right, turn 180 do the same and carefully 'drag' springbar towards your intended
holes & they will just drop in, if you're careful. You could invest in a proper tool if you are so inclined.
Lovely watch, enjoy.
