I do not know a single other technical person who has a smart watch, I don't have one and have no plans to buy one, none of my technical friends do either. In fact the only people I know who have a smart watch are my brother (a chef) and a couple of people who work in sales.
I stopped wearing a watch around about 1998 when I got my first mobile phone. Since then the number of things that have a clock on them has only gone up. Everything else I can do better on my phone.
