Do you have any idea why the 6am fluctuation occurs ?
The date change fluctuation at midnight is presumably as the watch has more "Work" to do moving the date wheel.

I find that the spring is quite strong, definitely stronger than in the 3135, the lubricant giving issues is also a problem. This can definitely significantly impact amplitude at certain points.

So this would seem to be another reason that far more 3235 come through vs 3230, since this whole assembly is absent on the latter.
Could it be that there are actually multiple independent issues that all cause the same eventual outcome?
