First impressions of the Apple Watch Series 6 have now been shared by select media outlets and YouTubers, providing a closer look at the device's...

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 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.

“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

Such a handy, easy to use watch. Great features that help you out everyday

The Apple Watch Series 6 isn’t a huge upgrade over the Series 5, but it does enough to keep Apple’s wearable firmly in the lead.

New colors add newness to a timeless design, Excellent mix of foreground and background features, Impressive array of features and sensors

Battery life hasn’t improved, On-demand blood-oxygen readings are finicky

Love being able to see notifications without taking my phone out, the fitness features are useful and motivating.

Love the watch however one part of the band does not click into the watch head itself. I took it to my nearest store and they advised that I had to send the whole watch back to apple for them to replace the band. This was inconvenient as i had spent hours setting it up and syncing to phone. I was not prepared to send the whole thing back so I've kept the dysfunctional band. I have had to purchase alternate bands elsewhere.

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

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
