When you whirl the clock around your head, it does indeed count 60 Hz pulses and doesn't miss any. Therefore, the clock does not run slow as SR predicts. So, the clock is wrong. It happens because you aren't whirling the "clock" around your head, you're only whirling its display. The timebase is at your local generating station, which is not whirling over your head.
