Apple Watch Series 6

The innovative blood oxygen sensor, the ECG app, and the Always-On Retina display make the Apple Watch Series 6 the most advanced smart watch on the market.

With this state of the art watch on your wrist, you will stay connected wherever life takes you. It will elevate your fitness experience and provide you with crucial health data.

Apple has managed to take all the advanced features of the Series 5 – impeccable design, elevated fitness features, life-saving health tools, slick notifications, and apps – and add even more greatness to it.

If you have no budget restrictions, the Series 6 is definitely worth the splurge.

The Apple Watch Series 6 offers improved integration with the iPhone and a performance level never seen before. It exceeds all other competitors in user-friendly health-tracking functionality and is extremely comfortable to wear.

The only drawback can be the sleep-tracking functionality, which is a bit too basic for this world-class smart watch. Some tech experts think that it is not worth wasting precious battery life on it.

  • GPS model lets you take calls and reply to texts from your wrist
  • Measure your blood oxygen with an all-new sensor and app
  • Check your heart rhythm with the ECG app

Apple Watch SE

The Apple Watch SE offers the same larger display as the Series 6, fall detection, emergency SOS for your safety, and an always-on altimeter for a much more affordable price. Or, as Apple puts it, the SE is heavy on features and light on price.

Although it is technically a new model, it is not entirely new inside and out. Apple has taken the same design, performance, and capabilities from Series 4 and added a couple of minor innovations. SE will not be able to measure your ECG. However, it comes with an always-on altimeter, which, of course, will not deliver the same result.

The Apple Watch cannot brag about its battery life (sometimes failing on you midday). However, surprisingly enough, the SE Series sometimes even surpass Apple’s 18-hour claim, and you can log a full night of sleep and still be able to use it for several hours in the morning.

The lack of ECG and blood oxygen tracking sensors in SE should be a deciding point only if you are particularly worried about your heart. The lack of an always-on screen, however, can be a deal-breaker for some fitness enthusiasts.

  • Large Retina OLED display
  • Up to 2x faster processor than Series 3

Apple Watch Series 3

This model comes with the main health, fitness, and connectivity features of the Apple Watch.
Due to its iconic design, the Apple Watch is one of the most recognizable timepieces. With this iconic design, you do not feel the need to upgrade it as often as with the iPhone.

Series 3 vs. Series 5

The release of the Series 5 has made the Apple Watch Series 3 significantly more affordable. However, if top-notch medical apps and an enhanced display speed are essential for you, the Series 5 is a good investment. It offers advanced features, including a larger always-on display, a compass, a faster processor, and superior health features such as an FDA-cleared ECG app.

That being said, if what you’re after a good quality smart watch that communicates well with your iPhone, then the Series 3 does a great job.

The Apple Watch Series 3 remains the right choice for those looking for a solid iPhone-compatible smart watch but don’t want to pay the hefty price of the Series 5. With Series 3, you still get precise sports and fitness tracking and many of the latest watchOS six features.

Final Words

While a larger display undoubtedly makes it easier to view any content, you can not ignore the size of your wrist. If you have a pretty slim wrist, most larger models will not look and feel comfortable.

Before making a decision, it is good to go to the nearest Apple store and try all available sizes in person.
