I’ve made myself stop wearing a watch. My iPhone has a clock on it that auto syncs to the network. And, as I travel so much, that comes in handy. My iPhone is always showing the timezone in which I currently am located, unlike my watch which requires a manual change. I’ve gotten comfy going without the watch.
But this watch, with tiny lasers to indicate the hour and minute hand, would be enough to make me start wearing one again!
