I fully agree with you, if he would not have gone to the AD, who measured low amplitudes with their timegrapher, he would not have seen any sign of change.

That is exactly my point, timekeeping remained constant for his 124060 Submariner, and he was blind (without any instrumentation) to see that the 3230 movement amplitudes decreased rather quickly (in about 10 months). Only the AD could see this on his timegrapher.
The 32xx decrease in amplitudes - I do not speak about the normal reduction of amplitude during the 72 hours of power reserve but compare max. achievable amplitudes after a full winding - is much quicker compared (for example) to the 31xx movements. That is the main reason why many owners cannot see that their movement is sick because timekeeping remains very good for a rather long time, even if amplitudes of only about 200 degrees are reached after full winding. As soon as the amplitudes decrease further, let's say to 180 degrees (I have timegrapher data to demonstrate this) then timekeeping starts to degrade significantly and everybody can see the movement problems because the watch loses more and more time. This can develop rather fast (a few weeks or months). Such a fast degrading behaviour I have never seen with other calibers.

Nobody here can know when this 3230 was assembled and tested, any time in 2020 or 2021.
