The Apple Watch Series 3 is still a very good device, in my opinion. Sure it lacks some of the new features and AOD, but the battery life is still solid, and for what I need is more than enough. It’s still fast enough, and even using it to measure my sleep every night, I still get 2 days out of it. What do you think is what I miss the most while keeping the older model? I know the newer watches are more advanced, faster and prettier, but I do not feel that much has changed in recent years.
