I bought mine refurbished from Amazon. Despite being refurbished it looks brand new and may have well have been factory-sealed. If you have an iPhone, it is extremely easy to set up. You just pair it with your phone and it connects to your account and basically sets everything up automatically. You have the option of having it download a bunch of apps at one time, or you can pick and choose apps to download after the watch is set up. I have used it mostly for workout and sleep tracking, but there are a lot of other apps specifically for the watch available. I have not come across any issues with it having been refurbished, and getting it that way is much more cost-efficient than getting it brand new.
After a couple of years, the face plate popped off. It actually still worked, and I could use a rubber band to keep the plate in place, but I did not want to do that long-term, and I was leery of using superglue on it. Because it was out of warranty, Apple wanted $600 for the honor of sending it in to get fixed. So, needless to say, it was a lot more cost-effective to purchase a new one. I do not think the face plate popped off because it was refurbished. I just think that is a thing that happened with the older model. So far, I have had no issues with my new watch.
