A week or so ago after cautiously dismantling, cleaning and lubricating, I managed to put life back into an old and unwanted Seiko automatic (with the invaluable help of the forum - and it is still working). I now need to know how to go about setting its consistent accuracy.
Is it simply trial and error?
In some instances adjusting the balance wheel regulator causes the balance spring to catch on the stud holder, seeming to deform the balance spring and stop the watch altogether. At which point I freak out, set things back to what they were before and have an inaccurate watch (+/- 5 minutes per day)
Whilst it must be a matter of finesse and incremental movement I would be grateful for any tips people may have come across in their experience to set both me and the watch on the right path.
Many Thanks again.
