I currently have a S0 Apple Watch that I bought when it was released in 2015. It’s definitely showing it’s age as the battery barely lasts through the day and the device often stutters while in use. I use the device mainly for notifications and don’t really care about the fitness tracking. As all models will support this, I don’t really want to pay extra for features I won’t use, but also want a model that will last a few years of os updates. The series 1 is appealing as it doesn’t cost much, but I’m worried it won’t get many more watchOS updates, so I’m unsure if I should get the series 1, 3, or wait for new models to be released. Any thoughts?
