I Just got an AP ROO black theme, and i brougth it down to my local watchsmith to service the Asian 7750, then he told me its a waste of time... lol he told me its either you keep it like this since the mouvement is according to him cheap and not made with quality parts or he could upgrade it to a Swiss Eta 7750, and that mouvement costs 700 dollars, do you think its a good investment guys or i should just get it serviced by one of our modders on the forum....
