To be able to observe the hands of a moving clock, it would have to be moving far too slowly to make any difference at all.

According to SR, you the SR observer predicts the clock is moving at s slower rate by a factor of 1/gamma. The direction of motion wrt you has no effect on this prediction. According to IRT the moving clock is predicted to run slower by a factor of 1/gamma or run faster by a factor of gamma. But only one of these prediction is correct.
