Alongside the iPhone XS , iPhone XS Max , and iPhone XR , Apple used the special event at the Steve Jobs Theatre in Cupertino earlier this week to unveil the Apple Watch Series 4 . The launch represents the biggest redesign to Apple's smartwatch since its introduction in 2015 .

For pretty much as long as smartwatches have been a thing, the Apple Watch has been treated by many as the gold standard.

Incredibly smooth software experience; Great look and feel

You have to own an iPhone; No ECG in Australia

This new Series-4 Apple Watch is a huge improvement over my old original Apple Watch Series-0. Love the larger screen and new faces with more complications. Also, the expanded heart monitoring with ECG is fantastic. This new watch is waterproof where my old one was not. Nice upgrade overall.

This is my first Apple Watch, and I can't figure out how I've lived without it! I exercise a lot, and even through multiple workouts each day, texts, phone calls, playing music, emails, GPS, etc., I always have at least 50% battery left at the end of the day.

Good at tracking steps, and helps to stay motivated for fitness goals; Love that I can text from it and also use my google maps on it

No bad things to say - worth every cent

Apple's smartwatch has finally hit its stride

Stunning looking display; Best smartwatch out there; watchOS 5 is great

Expensive; Lack of third-party Watch Faces; Unclear when ECG features will come to Canada

The Apple Watch Series 4 is the first over-the-counter consumer product that can be used for an electrocardiogram reading. At present this heart-monitoring feature is approved for the US market only, but it will notify you if your heart rate is too high or too low.

A great improvement over peavies Apple Watches and all other fitness watches in general, this Series 4 is working so well for us that everyone in the family is get one this Christmas. It's thinner and more comfortable than ever, making it effortless to wear all day long.

Earlier Apple Watches were impressive wearables, but the new Series 4 is the strongest argument yet for wearing a smartwatch. And that's not just because of bigger, edge-to-edge screen or its improved fitness tracking either.

When Apple first introduced the Apple Watch way back in 2015, it wowed, but was also a major disappointment for some consumers the world over. This was a rare instance when an Apple product had polarising opinions across the board. At the time, people did not know what to exactly do with it.
