Question: what is the difference between the apple watch series 4 and the apple watch series 5?
Answer: Naturally, the Apple Watch Series 5 is better than the Apple Watch Series 4, but it's a minor upgrade. There's the always-on display, more storage, the compass, and a couple of extra (very expensive) options for the body material. If you already have an Apple Watch Series 4, then you really don't need to upgrade.
