For years, Apple has been releasing smartwatches claiming that the newer model is an upgrade of the previous generation. However, only this year’s Apple Watch Series 4 has the right to be called an upgrade for it is the first true redesign in the series of watchOS devices.

If you’re on the fence about buying the all-new Apple Watch, we’re here to assure you that purchasing one is a wise move. The Series 4 does not only come with a bigger screen, it also has features that could save your life if you have heart problems or if you were to fall.

The Apple Watch Series 3 was already a remarkable device given its cellular connectivity, W2 wireless chip, water-resistant body, barometric altimeter and super-fast dual-core processor. The Apple Watch Series 4 has all of these features baked into it alongside substantial upgrades, as pointed out by Fast Company.

The display on Apple’s new smartwatch is significantly bigger than its predecessor’s, and it’s all thanks to the removal of the black bezel space around the screen — a redesign move that the Cupertino giant also adopted for its newer iPhones. The bigger screen means more room for “complications” or the bits of useful information the watch shows.

With the Apple Watch Series 4, users can readily glance at a larger set of information. The redesigned software interface also gives the device a more distinct look that definitely sets it apart from older Apple smartwatches.

When CNBC’s Todd Haselton reviewed the wearable, he appreciated the expanded display the most. “I love the larger screen — it’s much easier to see. Apple takes advantage of this with new watch faces that show a ton of info, like the weather, the time, the date, your heart rate and shortcuts to Apple Music,” he wrote.

Apart from the edge-to-edge display, the all ceramic back and physical haptic feedback to the Digital Crown make the Series 4 an impressive upgrade if you are switching from Series 3. The watchOS 5 operating system also complements the Series 4 with its performance improvements, new watch faces, Siri enhancements and so much more as per AppleInsider.

Nevertheless, the biggest reason for you to upgrade to the Series 4 has to do with the device’s health-centric features. The ECG feature measures and reports readings of heart rhythm. This comes in handy to users who may be unaware of an abnormality in their hearts’ functioning.

Another neat feature is the improved accelerometer inside the Apple Watch Series 4. This can detect if the wearer had a fall, and it will automatically alert the user’s loved ones. This may be a feature that will rarely be used, but it will be a lifesaver in the most dire situations, according to ArsTechnica.
