What is the trick to repositioning the minute totalizer on an A7750 (the hand is NOT loose)?
I removed the rotor & auto-wind gearing on an A7750-powered 6263, but, upon reassembly, I found the minute totalizer was resetting to -59 minutes instead of its normal null position at 12. So I unscrewed the 3 screws & removed the auto-wind bridge again to check the positioning of the minute totalizer assembly. Everything was in its correct reset position
So I reinstalled the bridge, but found that the minute totalizer had moved again into this position
What gives?????
It may be difficult to see, but the hammer is properly contacting the heart-shaped gear on the minute counting wheel (the yellow colored wheel near 6 o'clock in the 1st pic), which is what sets the minute totalizer reset position. So it ought to reset to 12, but does not.
As we all know, the subdial hands on these watches are notorious for coming loose on their tubes & then resetting in different positions. So the 1st thing I checked was the hand. Perfectly tight, no play (in any direction) whatsoever. (The hand is NOT the problem.)
So, again, I removed the auto-wind bridge & checked the positions of the chrono components, but everything looks fine.
Am I missing something?
How did the minute totalizer hand move from its normal null reset position if everything in the chrono assembly appears to be normal & how do I get it to reset back to 12?
I apologize for the less than clear pics. I am currently without a macro shooter.
