I have the original Apple Watch Series 0 stainless with the leather loop and never had a problem with it. Every update I always restart the watch or reload it, which usually makes it run as new. Only had a slow down once and that was fixed by restarting the watch. Battery has been consistent with about 14 hours straight use every day before I have to charge it. I guess I was one of the lucky ones. I use the watch for messages, walking and calls once and while. But the most important thing I use it for is shopping with Apple Pay. I'm worried that since it will not be receiving anymore updates, the watch might not be safe to use. I use Apple Pay for almost all my shopping. I really wanted to hold onto the watch for another year or two and don't mind not getting the updates, as long as know that Apple Pay will still be secure through my watch. Remember, my watch still looks almost new and still runs great. So why would I want to update now. I hope I'm not forced to buy a new Apple watch because Apple won't guarantee safe use of Apple Pay on my series 0. Mind you, I love the Apple Watch and will get another one, but I didn't want to buy another one now. So my question is, "Will Series 0 by safe to use without any further updates (IE, for Apple Pay)?
