Not sure, if anyone here already asked this before. bit is it possible to replace a balance bridge and a hair spring on a VSF 3235 clone movement. the hair spring is not very reliable and the shock absorbing does not work very well on clone movements, sometimes it get out of place and stop the watch.
I have to open the watch just to blow air on it so it goes back the correct place. it may not even be cost effective to do this.
