gravity84

I'm nervous about replacing it myself though.  What all would I need?  Hand pullers, I have a case back opener...

how hard would it be?

Hi all, first post in here.  I have a Rolly Replica with a DG2813 in it.  It was stopping every minute or so even when fully wound so I tried to take a look and the balance wheel was what was stopping.  While trying to fix it i fubar'd the hair spring.  Should I just replace the movement or replace the part?  Maybe I should take it into an actual watchmaker, do they typically frown upon repairing replicas?
