If you are looking for the absolute best wearable to pair with your iPhone, this is it

Despite the new sensors feeling like a tick-box exercise, there's still no better smartwatch on the market. It's just that this time around it offers many features you'll want, along with many that you aren't aware you'd want, plus lots that you'll simply never use.

New dimmed display option, Display is brighter than before, Fluid performance, Lovely design options for both size options

No game-changing improvements over Series 5, Sleep tracking raises battery charging questions, Altimeter doesn't feel well executed, Why do we have a blood oxygen monitor?

Apple just made the Watch even better and although not a lot has changed, it’s still the best smartwatch you can buy.

Great performance, Great screen, Useful health features

Poor sleep tracking, Still have to charge every day

The Apple Watch S6 is the best all-rounder smartwatch on the market, especially for iPhone users, but there are better deals to be had.

Brighter display, Zero lag, Comfortable (even when sleeping), Faster charging

Could do with more use cases for bloody oxygen function, Battery life could be better, In reality, not a huge jump from Apple Watch Series 5

The Apple Watch Series 6 is the best version of the best smartwatch in the world. But it might not be the right device for you. The classier materials, new colors and always-on display are key reasons to buy, as are ECG and SpO2 for those looking for a health watch.

SpO2 and ECG, New colors, The best version of the best smartwatch

The Apple Watch Series 6 may seem like an incremental upgrade, but the introduction of blood oxygen monitoring is a game-changer. And the brighter always-on display is welcome. Yes, there’s not much different from the Apple Watch 5 to the Apple Watch 6, but the SpO2 monitor is a tool you might find...

Blood oxygen (SpO2) app, New colorful casings, Brighter always-on display, Faster charging

Same 18-hour battery life

The Apple Watch Series 6 boasts plentiful features that focus on health tracking and wellness. While it's an exceptional fitness tracker that comes with hundreds of app options to optimize your needs, it's not ideal for GPS tracking as its accuracy isn't as good in covered areas.

Excellent and numerous features, integrates across software platforms easily, easy to set up and use, sleek and low profile, quick updates

Poor battery life (both smartwatch and GPS settings), inconsistent GPS accuracy, difficult to find some features, can only be used with an iPhone

The Apple Watch Series 6 is the best smartwatch on the market for an iPhone. It has better integration with the iPhone and is fast, fluid and responsive in a way that many rivals simply aren’t.

Pros: excellent haptics, great always-on screen, ECG, great health tracking, great activity tracking, 50m water resistance, solid battery, comfortable, quick-swap straps, Apple Pay.

Cons: expensive, only works with an iPhone, sleep tracking not great, blood oxygen data not that useful.

I've tried to steer clear in this review of the usual journalistic obsession with "What's new?" But in the final reckoning we simply have to acknowledge that not much has changed since the Series 5.

Apple Watch Series 6 might very well be the best smartwatch on the market – like the Series 5 before it. The “smart” experience remains fluid and useful while fitness features remain extremely easy to use and analyse. However, there’s little reason to upgrade from last gen.
