Apple Watch Series 3 Review


Update: You can now read our Apple Watch Series 4 review!


You could say that the hoopla over smartwatches has died long ago, they've kind of hit this unseen roadblock where consumers just don’t seem to be as interested in them as before. Initially, the pacing was ferocious, as a slew of companies were quick to deliver their offerings to our wrists, but as time wore in, we all soon realized that we're still constantly favoring our mobile devices as our go-to portal for connectivity. Through it all, though, the Apple Watch has remained the most relevant, with only a handful of others trying to keep pace – and that's despite the slowed interest in the segment as a whole!

The Apple Watch Series 3 introduces one major feature that aims to break the bond that has kept it tethered to its master, the iPhone. Now that true cellular connectivity is on board with the Apple Watch Series 3, is that, along with some other new features, enough to spark renewed interest? It's a tough market to be in right now, but somehow Apple's prized smartwatch has not only claimed the top spot in smartwatch sales, but it has gone on to become the number one selling watch – beating out timeless and luxury makers like Rolex.

Achieving that milestone is remarkable on its own, but is the Apple Watch Series 3 really pushing forward enough to make a significant difference?

To no one's surprise, the Apple Watch Series 3 looks and feels much like its predecessors. There's been no change to the fundamental design here, as it continues to favor the same square shaped design that's been in circulation since the very first one. While the square shaped style isn't the most fashionable, nor stylish by any means, Apple doesn’t seem to mind it because it's nonetheless distinctive – you see a square shaped watch on someone's wrist, it's more than likely an Apple Watch.

This year's lineup of Apple Watch Series 3 covers the same gamut in terms of finishes and sizes. From the standard aluminum frame available in 38 mm and 42 mm sizes, which starts at $329 for the non-LTE version and $399 with LTE, to the more premium casings like stainless steel and ceramic, there's a look for everyone to choose from. For those wishing to pick up a stainless-steel model, they start at $599 – while the ceramic finishes fetch upwards around $1,399. And if you worry about it getting wet, there's no need to fret because it features a water-resistant construction for up to 50 meters.

Just as before, there are two buttons placed along one side, the so-called "side button" and the crown. On its underside, we have the usual array of sensors to measure our heart rate. And finally, the bands are easily swappable as before. What differentiates the non-LTE models with the ones with cellular connectivity on board is the red dot slapped onto the side of the crown. We're unsure about this peculiar decision, just because it seems out of place and doesn't necessarily mesh with the rest of the Apple Watch's clean look.

Honestly, the design is something you're going to have to live with, even if you despise square shaped watch designs, seeing that this is the only presentable option for the foreseeable future. Apple has kept firm in essentially recycling its design, a tactic that doesn't seem to end any time soon. Now, that also has a bright side to it, because it means accessories are in abundance – and they won't cost you a penny like they did when the first Apple Watch was released. But still, it's a boring looking design in comparison to some other round-faced styles out there.


Looking at the specs sheet of the Apple Watch Series 3, it doesn't appear as though they've changed the display with this latest model whatsoever. Specifically, it's a 1.65-inch second-generation OLED Retina Display with a resolution of 272 x 340 pixel (312 x 390 with the 42mm variant). With our particular review unit, the one with an aluminum chassis, it sports Ion-X glass – while the stainless steel and ceramic models get the stronger sapphire crystal for protection.

There's very little to nitpick here, seeing that it has all the favorable qualities in making it usable during all sorts of situations. For something leveraging OLED technology, it doesn't appear to exude the over-saturated and high-contrast tones that the technology is known for. That’s a good thing because not only does it deliver an ample level of brightness under direct sunlight, but it's never overpowering to the eyes in dimly lit situations either. From a normal viewing distance, there's enough detail and clarity to see everything that's on-screen.

When you have such a small footprint to deal with, it doesn't take a whole lot to make it enthralling. At the very least, the display in the Apple Watch Series 3 has everything you want in a smartwatch display. It's incredibly detailed and sharp, offers exceptionally wide-viewing angles, colors have a neutral tone, it's visible in outdoor settings, and it doesn't strain the eyes. And yes, the same Force Touch mechanism is still in play here.

Interface and Functionality

Much like with any new product release, the arrival of the new Apple Watch Series 3 sees a new version of Apple's smartwatch software – WatchOS 4 in this case. Frankly, most people probably wouldn't notice any major shakeups between this version and the previous one, especially given that the new software has been out for almost a week to other Apple Watches.

From the way the interface is laid out, to its focus on fitness, WatchOS 4 receives small, iterative improvements that fine-tune an already robust ecosystem. Compared to other smartwatch platforms, Apple's WatchOS is undeniably the most feature-rich and well-executed, far more intuitive and informational than its rivals. Seriously, the best part about WatchOS as a whole is that it's not just a platform that aggregates notifications, but rather, it's a complex one that allows the Apple Watch Series 3 to truly achieve freedom.

We'll talk more about its untethered abilities later on, we promise. Anyone that's owned an Apple Watch would find difficulty in uncovering all the new features with WatchOS 4. For starters, more emphasis has been placed on fitness with this version, improving upon what it has offered in the past with goals that are personalized to you. With the Activity app, you can now easily switch between different kinds of workouts to track. One of the more notable ones is the high intensity interval training (HIIT)

Aside from that, watchOS 4 introduces an improved Music app. It will automatically import new Apple Music playlists, with multiple playlists also being supported. Finally, there's an overhauled app dock which will let you scramble through your apps by simply rotating the dial on the side.

Functionally and visually, WatchOS 4 recycles the same recipe as before. Even though its new features aren't overpowering or in-your-face, it doesn't need to be because it's still the most intuitive, functional, and practical smartwatch platform around – more so when the competition is moving at a slug's pace.

When other smartwatch platforms continue to simply act as a depository for notifications and such, WatchOS 4's minute improvements are still leaps ahead of everyone else.

Processor and Memory

Being the newer model and all, most of the Apple Watch Series 3's improvements come in hardware form – not the display and such, but rather, the processor that's the brains behind the scenes. With this year's model, it leverages a newer, more powerful dual-core S3 chipset, which is allegedly 70% faster than the Series 2. That's debatable, of course, seeing that the same responsive consistency is evident on both smartwatches. Don't be shocked if we believe that there aren't any noticeable differences, mainly because it's really tough to gauge them.

Apple's platforms have always been optimized to deliver the smoothest performance, and the Apple Watch Series 3 doesn't disappoint. From its tight, responsive scrolling through lists, to instantly answer our commands with Siri, there's barely any pause with its performance.

Additionally, the Apple Watch Series 3 packs double the amount of storage than its predecessor. It's been bumped up to 16GB of internal storage, which should do nicely if you intend on storing music on the watch itself.


Untethered, that's now something we can say about the Apple Watch. Consumers were probably screaming for this feature since day one, but it took Apple until now to finally offer it – and it's not without its quirks at the moment. Previous to this, the Apple Watch was able to place phone calls, send text messages, and much more, but it still required an iPhone for that functionality. With the introduction of LTE and UMTS connectivity, the Apple Watch Series 3 can now access its own data stream independent of the iPhone.

Meaning, you can leave your iPhone at home and continue to use the Apple Watch Series 3. During our initial setup, we opted to choose cellular connectivity with Sprint's network, which requires a monthly charge of $15. That's a bit steep compared to its rivals who only require $10 per month, but Sprint does offer a free 3-month subscription, as well as a $5 discount if you subscribe to its autopay feature.

After getting it all set up, we ran into the nagging issue of it not working with cellular connectivity – it seemed as though phone calls and text messages were being routed to and from our paired iPhone. We verified this by placing the phone into airplane mode, and then proceeded to move to another area free from any associated Wi-Fi hotspots. Eventually, the connection seemed to suddenly fix itself. And from then on, we were able to place and receive phone calls via its cellular connection.

Another issue we experienced later on pertains to some third-party apps, Twitter and Instagram to be exact, which were unable to work properly. From the looks of it, the native apps all seemed to work fine on both cellular and tethered via Bluetooth to the iPhone, but these two particular apps just couldn't work. Our guess is as good as yours most likely, which could be related to the carriers, Apple, or just some weird glitch that'll hopefully resolve itself with updates.


There's nothing different whatsoever here with this category, since the Apple Watch Series 3 is only capable of acting as a remote viewfinder and shutter for your iPhone's camera. Running the app, we can visualize the composition of the shot – while still having access to all the same features from before. This includes things like tap-to-focus, switching to the front-facing camera, and enabling the flash/HDR. Naturally, it's a useful tool for all sorts of shooting applications.


Most of the Apple Watch Series 3's multimedia functions limit it to being nothing more than a remote tool of sorts. From watching YouTube videos on your iPhone, to playing some music through the Pandora app, the Watch's main function is being a remote – allowing us to pause, reverse, and adjust the audio levels. While there is a Photos app, it can only scroll through content that are synced with specific albums. Well, that's pretty much the extent of what it can do in the multimedia front.

The big new feature in this department is independent Apple Music streaming with the Watch Series 3, but it's going to become available via an update at a later time, probably sometime in October.

Call Quality

Convenience is wonderful, especially in situations when you leave your iPhone somewhere or during emergencies, but when it comes to conversing with the Apple Watch Series 3, it's not the most suitable thing because of how it can be easily overpowered by noise in the background. While callers were able to decipher our voice on their end, it required us to talk very closely and loudly to the microphone. Hey, it's not the best quality, but we can't deny the convenience brought on by the new cellular connection.

Battery Life

If we're to comb over the specs of the new Apple Watch, you'll probably realize that Apple claims that its new model achieves the same battery life as its previous models – upwards around 18 hours to be exact. We can report, however, that the Apple Watch Series 3 definitely provides ample battery life. In most cases so far, we've been able to reach close to two full days from a single charge with mixed usage. Unless you're strictly using cellular connection, which definitely eats up more of the juice faster, you won't have the need to charge it nightly. Using the included charger, it's able to recharge fully in about 1.5 hours.


There's no denying that the Apple Watch is the best-selling smartwatch out there. If you're uncertain about that, all you need to do is just go out in public and check for yourself. In most cases, you'll probably see the Apple Watch on a few people's wrists. However, we have to remind ourselves about what's new here with Series 3 – and whether or not it's worth the cost.

Out of everything that's new with Series 3, it's undoubtedly its new cellular connectivity that stands out the most. Call it a long time coming, but it's finally here. However, it's a tough sell when you consider that you're basically just obtaining true independence from this. Certain situations merit the ability to stay connected exclusively through an Apple Watch, but for those that are never too far away from their iPhones, it's an expensive investment to justify upgrading from a previous version.

That becomes more apparent when the core experience and functionality of the Apple Watch doesn't differ from its previous iterations. And that becomes more convincing if you compare the non-LTE version of the Series 3 watch against Series 2. Slapped with a starting price of $399 for the model with LTE connectivity on board, or even $329 for the non-LTE version, the Series 3 Apple Watch is a tough sell.

Still, that's damage you'll need to endure to experience the richest, most robust smartwatch platform around. Fundamentally, not a whole lot has changed here with the exception of cellular connectivity on board, a few new features with WatchOS 4, and some minor hardware upgrades under the hood. You're paying mostly for that independence, so if that's worth it to you, then this is your best option. If not, stick with the older models and save yourself the money.
