So, there it goes. I'm now feeling phantom vibrations even when wearing my analogue watch!! Back when mobile phones became popular, people learnt to pay attention to vibrations, or our brains did. We never evolved to feel vibrations, so it was something new. After phones, any tiny vibration would be perceived by us, such as the gentle movement clothes makes when rubbing against your skin. So after only 3 days wearing an apple watch, and after returning it today ( I never wanted a 38mm..), I can feel "notifications" all the time now. Oh dear..
