Ewhite,
Make sure the balance is oscillating at the proper frequency. If you have an electronic beat counter it will simply flash the counts (18,000/hr) on the screen. if not, you can do it the old fashion way and time it manually with an electronic watch. The oscillation of the balance is the heart of the timing process and if it is not right, then the rest of the watch wil be wrong no matter how mechanically perfect it is.
