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?

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 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.

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

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.

The Apple Watch Series 6 continues Apple's smartwatch dominance, with solid improvements across the board. Many of its features can be found in cheaper competitors, but not the overall experience.

Great range of health sensors, Brighter always-on screen is impressive, Excellent app support and software, Solid battery life for general use, Great new colour options

iPhone-only still, Not a big leap forward from Series 5, New sleep tracking is basic, Won't satisfy truly hardcore fitness fans

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.

With an unrivaled user experience, fantastic apps, and potentially lifesaving health and fitness features, the Apple Watch Series 6 is the best smartwatch you can buy.

Measures blood oxygen saturation (SpO2) on demand, Always-on altimeter for real-time elevation tracking, Improved wrist-down screen brightness, WatchOS 7 adds a handwashing countdown timer and sleep tracking, Fast new processor, Best third-party app selection, Attractive new watch colors and band...

Expensive, Offers only a slight battery life improvement

“The Apple Watch Series 6 is the most complete smartwatch package you can buy, and if you want the very best of everything Apple's wearable offers, it's the one to get.”

Comprehensive health and activity tracking, Reliable software, Always-on screen adds visual appeal, New blue, red, and gold colors look great, Apple S2 chip is a powerhouse

ECG and SpO2 measurements have limited real-world use

Unlike most other smartwatches on the market, the Apple Watch Series 6 boasts a sleek rectangular design with a ceramic rear panel. Sitting on the left is a speaker and on the right is a button, microphone hole, and a digital crown that offers haptic feedback.

Always-on-Display is very bright, Feels really fast, Quicker charging

Sleep Tracking is limited, Blood Oxygen monitoring could be more useful, Battery life isn’t amazing
