Sport, 42 mm, black Sport band but silver aluminum case. First Apple product I ever lost. At the pool. Probably stolen by now. I didn't have a passcode on it, but I also didn't set up Apple Pay on it. Do I have to worry about anything security-wise? Really don't know what info the Watch actually stores in memory....Hopefully whoever finds it will just wipe my data from it.... Also...I guess I should just wait till they have decent location/wiping software for the watch, before I get a new one? total bummer.
