Broke my submariner

[smcintos]

I'm partially paralyzed so I have to wind my Sub manually every few days. The last time I was winding the watch something seem to break free and now the crown just turns freely. I can no longer wind the watch and I cannot change the time or date. Does anyone have any idea what I could've broke and what those parts might cost. I'm already getting ready to send it to Vanessa just wanted to get an idea first. Thank you in advance
