Advice Needed About Crown Stem And Hands

[Guest Teedotyyz]

So I had the good fortune of dropping my watch onto my kitchen floor the other day. Two of the small hands fell off; other then that it seemed to suffer no other hardship. Being an idiot, I broke the crown stem off of the crown. What I am looking for is advice on how to remove the remaining stem and possibly where to get a replacement. Is it as simple as pushing that teeny tiny little button there? Also, is there a trick to putting the hands back on?

Although it is a cheap watch, I am quite fond of it so any help would be appreicated. Here is a picture of the movement.

Thanks for your help. Tim.
