Now I wear a watch all the time.

I'm not really a watch person in general, whether it be a smartwatch or not. However, I had the opportunity to participate in a study trial that incorporated the Apple Watch. And after a week of usage, instantly wanted one! The health tracking features are highly impressive. Super accurate heart, sleep, and activity tracking. That includes steps, elevation, even calorie burn. This one is the GPS plus cellular model. You can even leave your iPhone at home if you want to go out for a jog or make a quick run to the store without worrying about if you have your iPhone or not. The cellular radio is absolutely great. It maintains great, reliable service, as well as the GPS is shockingly accurate! And what's more impressive is just the convenience that the Apple Watch brings. The extension that it gives your iPhone is super convenient, to where you'll actually notice that you'll be taking out your iPhone a lot less for things like checking messages and email, Apple Pay, which is a main one that you'll notice. Even controlling your smart home. Now, more often than not, I control everything in my condo from the watch instead of reaching for my iPhone. Absolutely love the natural titanium and radiant gold titanium watches with the sapphire crystal display. Especially the sapphire. Trust me, you don't need a screen protector with a sapphire cover. This watch gets bumped a lot. No dings, dents, or scratches. And the Milanese loop is lovely. You can get a lot more granular adjustments with the magnetic clasp. If you're on the fence about purchasing one, trust and believe. You won't regret it. It's a lovely companion to the iPhone. I have the watch on all the time, so I guess I'm a watch person now, LOL.
