The Apple Watch Series 5 is another step of Apple's relentless pace at the head of the smartwatch pack. The new model takes everything that made the Apple Watch Series 4 so good, sprinkles on a few extra features, and then replaces the previous model with this superior one.The stand-out new feature is an always-on screen, which means you don't have to raise your wrist for the screen to show something: it will still show your watch face or workout at all times, just dimmed.And with a few other features to hand, plus new software, it's a small but notable upgrade over last year's watch.So is it worth upgrading to, and should you make this your first Apple Watch? Here's our in-depth review with everything you need to know.

The Apple Watch Series 5 has a new processor, called S5, that replaces the S4 used in the Apple Watch Series 4 (see if you can crack that naming code).But despite the processor having changed enough forApple to give it an updated name, don’t expect to notice any difference from it: the new features are all about efficiency, rather than extra speed.The changes are all focused around things like the addition of the low-power controller for the always-on screen, and other ways of saving power to balance out the extra energy usage.

The good news is that the Apple Watch didn’t actually need any extra speed, so I’m fine with this – I never found myself bottlenecked by the Series 4 when loading an app itself (though sometimes when fetching data within apps, but that’s more of a wireless responsiveness thing).
