In the growing lineup of new Apple Watches, I see only two options worth considering of the three: the Series 6 and Series 3. There are two main reasons to buy an Apple Watch: health and fitness or a fun complimentary phone gadget. Those both leave the Apple Watch SE in a strange place.

Quicker-charging battery with same all-day life., Brighter outdoor display., Sleek new colors., Same great tracking abilities with a new sensor for SpO2 and the tried-and-true ECG., More activity tracking modes added to an already long list.

Sleep tracking is less detailed than competitors' while being no better than any of them., Activity trends could still use more guidance., Family Setup seems rather pointless; give us Android phone compatibility!, Aging looks, even with new colors., Still an expensive watch.

When it comes to smartwatches, it’s Apple against the world. It’s not that there aren’t plenty of other products to choose from — it’s more that the company has just utterly dominated the space to such a point that any other device is relegated to the realm of “Apple Watch alternatives.

Longer battery life and faster charging; stunning new colors; potential to be an even more capable health tracker

The potential for deeper sleep analysis and even more advanced health-tracking is unrealized—for now

Apple debuted the new Apple Watch Series 6 earlier this month and I've been testing out the new (PRODUCT)RED 44mm GPS model. At first glance it doesn't seem much different than the Apple Watch Series 5 , but there's more than meets the eye.

Gorgeous, refined hardware, Bright and useful always-on mode, Blood oxygen sensor, Sleep tracking capability, Excellent third party application support

Expensive, Battery life about the same as Series 5, Limited sleep details

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 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.”

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

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
