I have a watch I am trying to phase. Fingers are aligned properly. Drop off I have had to estimate because the Tuning Fork does not pull back enough to see when it would theoretically pull off the index wheel but I believe it is close to the 6 to 8 tooth number. The problems that I have are:
1. When low voltage phasing, the index wheel does not stop turning when going from 1st to 2nd phase or any phase for that matter. Current is well within the OK range for 1.55 volts.
2. If I ignore the fact that the index wheel is suppose to stop between phases, once the movement is spinning at normal speed and I case the movement with a 1.55 volt battery, the watch gallops.
3. The Vibrograf reading is -5.6 seconds which is low but well within regulation limits.
4. When I try to High Voltage Phase, the index wheel DOES stop between phases at the 1.055 volt reading, but, when I increase the voltage to 1.75 volts, I can not slow down the index wheel unless I go way past the lower voltage finger setting. Current at the 1.75 volt input is high at around 10 microamps.
5. Low Voltage Phasing is being done at the Low Amplitude Setting and High Voltage Phasing on the Read Microamperes Setting.
a) The Vibrograf is telling me that I the fork is vibrating correctly and that I should be losing 5 to 6 seconds per day as long as the watch is phased correctly. Right?
b) No hesitation between phases during LVP is telling me what? I am stumped.
c) The fact that I can get the movement to run at the right speed when Low Voltage Phasing, but, when cased, the movement gallops with a 1.55 volt battery battery installed is telling me what?
AS always, thanks for the help.
