I have a new best friend. It’s the Apple Watch Series 4. Boy, do I love this miraculous little machine. The new Apple Watch really is wonderful. As with everything else, speed makes it so much more fluid and seamless. The display is gigantic and awesome!

We've been fans of the Apple Watch since the very first version, but most people are not like us. And this is a product line that's needed to work hard at broadening its appeal.

Has there been a learning experience for Apple quite like the Apple Watch? Back when the original model launched in 2015, there was – not unfairly – a sense that Apple itself wasn’t quite sure what exactly it should do.

Mesmerizing new display, Fast and smooth performance, Health features could be game-changers, Battery life hasn't suffered

Siri still falls short, Expensive

The Apple Watch 4 brings some significant upgrades over the Series 3. For one, we have a slimmer casing, slightly bigger screen size and improved pixel count, offering much better screen visibility.

“The best smartwatch you can buy, a genuine improvement over previous models, and Apple’s finest hour in years.”

Short battery life

It isn't any one feature, ok, yeah, the display, but seriously, that sets the new Apple Watch apart. As always, it's the sum of the many moving parts, each getting better and more polished as hardware and software moves on.

W hen the Apple Watch debuted four years ago , there was quite a bit of skepticism from the traditional watch industry, media, and enthusiasts alike. Personally, as many aBlogtoWatch readers know, I was enthusiastic about it from day one and continue to be so to this day.

All in all, the Apple Watch Series 4 is a very impressive bit of kit. Not only is it able to accurately track a host of workouts - being intuitive and a pleasure to use throughout - but it is also a beautiful and super premium lifestyle device.

Larger display, slimmer chassis, gorgeous design, lightweight, smooth performance and navigation

Pricey, battery life still only 2 days, won't track sleep natively, no always-on display option

It’s bigger, it’s better-looking and it could save your life

The larger screen (30% larger no less), especially as the Watch itself has barely grown at all. The Series 4 comes in 40mm and 44mm versions (measured vertically), compared to 38mm and 42mm for past Watches.

There’s no native sleep tracking, and even if there was the battery life is still too short to allow you to wear the Watch at night. The battery will last a day comfortably, but not two, so you have to plug it in every night.

If one were to pull out a feature comparison of the Apple Watch Series 4 versus the Series 3, specific to sports and fitness, they’d likely just go ‘shrug’. Ultimately, the differences just aren’t there in the hardware side of things.
