Two things I never go far without. Glasses and watch. I am Mr magoo without glasses but the watch is a funny one. With it a rarely check the time without it and I get a bit antsy to check the time. It's not that it's better with it, it's just that time becomes a cause of anxiety without a watch. I hate being late and my life revolves around time in the week. Time to get up, to leave the house, to catch the train to get to work, to have first break, time for lunch, time for that meeting, time to call someone, etc. That leaves a need for time device. I prefer not to use phones for time as they're bulky things these days. I can't use my laptop at work because I'm not at my desk all the time. A watch is the practical device.
However, I don't quite know whether I feel better with it than without it. I would love to be without it. I've been wearing n one since 10 yo. I even believe wearing watches has made the wrist I wear it on narrower than the other but that could be the difference between dominant hand and non dominant hand whose wrist my watch goes on.
