The updated Series 4 Apple Watch is a fantastic wearable. The bigger screen makes a huge difference, as do the niceties such as the haptic feedback when you turn the crown. WatchOS 5 is by far the best of its type, and its easier and speedier than even on the Series 4. You might not use all its features, but you'll find a subset indispensable. We can't yet test some of the health features, and would advise anyone tempted by the ECG feature to wait until it's available if that's your main reason for buying. Although there's an LTE version, bear in mind you'll still need a compatible iPhone to use an Apple Watch. And now that the Series 3 has had a price drop, it makes the Series 4 look pricey. But if you want the best, this is it.
