Even before I knew this was a thing, I know I've looked at my watch and for a second being confused about why it seemed broken when it was working just minutes ago, simply because the second hand didn't appear to move in time.
I had assumed that this was part of my watches' mechanisms that self-calibrated but it never occurred to me that I just happened to notice this self-calibration so often!
It's interesting that I casually came up with a complex explanation and didn't even try to critically examine whether it was plausible or not.
