Pet4aYou only need the "smarts" to activate the time-keeping function of the watch. Then just uninstall the app from your phone, and the watch will never connect again. At ~$60 bucks, it's not a bad deal for a reasonably nice watch, with only one caveat: Connecting to the app is what allows the watch to sync with your phone network's time. If the watch you (might) buy loses or gains minutes, you'd need the app again, because there's no manual way to set it. I have two hybrids that I never connect via Bluetooth anymore (quit doing it about a month ago), and I haven't noticed any losing or gaining so far. I really only wear one of 'em anymore, but they're both right here at my desk and the one I don't wear is showing the exact same time as the one I'm wearing, so I think they keep pretty good time on their own anyway. The one I don't wear is a Skagen Hagen, different only in its appearance from the watch in this drop.
