When someone looks down at a swivelled wrist it is a universal signal of impatience.
I wonder if the inventors of smart watches have considered this. Do a Google image search for people checking their watch and everyone looks fed up, distracted or impatient. Now do a Google image search using the word ‘impatience.’ See what I mean?
For years glancing at a watch has been a gesture, mimed or otherwise, that is a value judgement on the context in which it is made. In a meeting it mostly says ‘hurry up’ or ‘I’m bored.’
