The design alone is a big upgrade, with the screen offering far more visibility, and while the health benefits are only going to help a subset of users, they're welcome and show the direction Apple is heading.

The Apple Watch Series 4 offers a larger, crisp display that shows more with less bezel, superfast speed and a louder speaker. It adds high and low heart-rate detection, fall detection with SOS trigger, and (eventually) FDA-cleared EKG for more detailed heart readings.

The watch face is not only bigger but also flatter, making it less bulky. And, thanks to sleeker bezels, there's no big, black border surrounding the enlarged display. And, like earlier models, the Apple Watch Series 4 is a champ when it comes to readability in bright and low-light situations.

What experts didn't like

ECG app not available at launch. Expensive

The Apple Watch’s battery capacity is unknown, but Apple says it will last for around 18 hours before it needs a recharge using the included magnetic charging disk. The quoted time is on the conservative side, depending on your use. If you’re using GPS, fitness tracking, or cellular, then 18 hours is at the top end, but with only notifications and turning it off overnight, we could almost reach 24 hours. Not great, but we’ve seen worse.

Siri is still unreliable. No always-on screen option. Complication options can be confusing

If it had better battery life, and thus able to track sleep, the Watch 4 could have been the perfect smartwatch.

It won’t last multiple days without needing a charge. Still won’t track sleep natively. No always-on display is irritating.

Starting prices are higher than last year. Battery life still won't last past two days. Watch face options are still very limited in choice and function. Only works with iPhones.

More expensive than ever. Transferring LTE service can be tricky. ECG feature isn't ready yet. Some watch faces feel like information overload. Rival watches have even better battery life.

No advanced sleep tracking. No always-on display option. No support for third party watch faces. Swipe to switch watch faces is annoying.

Running data still behind Garmin. New flush side button is harder to press
- T3
Lacks sleep tracking, commonplace in other wearables. Still no always-on clock. Super pricey

No native sleep detection; auto-detection for walking comes in too late

An Overview On Smartwatches

Watches have gone well beyond merely telling the time. You can read incoming texts and emails, monitor your health stats and even make and receive phone calls, all from the device on your wrist. But there’s more than one smartwatch player in town, and the choices can be overwhelming.

Chances are, one of the top deciding factors when choosing a smartwatch is the type of smartphone you own. If you have an iPhone, you’ll find the best compatibility in an Apple product. If, on the other hand, you own an Android-based smartphone, you’ll want to go with an Android-based watch. While most watches can pair with other operating systems, you’ll get the most out of one with the same operating system as your phone.

Then there’s the Fitbit line of fitness trackers. Once merely designed to measure the steps you take each day, these wearables have gotten much more sophisticated over time. Many models have a few of the same features as the iOS- and Android-based watches, offering functions like texting and contactless payment.

Your choice of smartwatch will probably be driven by your needs. If you just need health tracking, for instance, you may not get enough out of the other features to make it worth the extra expense. However, the price variations are minimal — especially if you’re open to an older model rather than needing to have the latest and greatest.

With smartwatches, many features are driven by the available apps. You can play games on many watches, for instance, but you may be limited by the apps that have been created for those versions. Before you buy, make sure the apps you want are available for whichever watch you’re considering.

After searching the app store, you’ll also want to consider the look and feel of each of the watches. Some models have a more traditional watch look, but you may find more bands you like in others. Since the faces of both types of watches are customizable, you’re sure to find a look that works with your own unique tastes.

The Smartwatch Buying Guide

  • You’ll be wearing your watch every day, so appearance is important. Taste plays a big part in this, but some watches have a more basic look. With some models, you can change out the digital watch face to suit your mood — or to match your outfit.
  • Some models build in advanced fitness tracking.
  • If you choose a watch with cellular built-in, you’ll be able to accept and make calls and texts even when you’re away from your phone. You’ll have to pay an additional monthly fee for that, though, in addition to paying more for the watch. To use this phone capability, you’ll need to have a device that’s compatible with the watch you choose.
  • In addition to phone functionality, you’ll also need the right smartphone to take full advantage of the watch’s features. Consider whether the smartwatch can sync with iOS or Android.
  • When you put your smartwatch on, you want it to run on battery power for at least the entire workday. Some watches will run for up to 18 hours on a charge. Some even promise battery life of up to four days, but this will vary depending on use.
  • If you own a smartphone, you’re probably already aware of the apps that are available for your operating system. The same situation will apply to your smartwatch. Some brands offer more apps than others.
  • Since you’re wearing it on your wrist every day, it’s important to find a band that won’t weigh you down. Some watches are as light as 1.12 ounces. Others weigh slightly more, at 2.88 ounces, while still others weigh closer to 5.1 ounces.
  • In addition to weight, it’s also important to consider how much real estate the watch will take up on your wrist. Some watches are available in two sizes, 40 mm and 44 mm, so you can choose the size that works best with your wrist. The display area of other brands is often smaller, totaling only 33 mm, or 1.3 inches.
  • One popular feature of today’s smartwatches is the ability to pay at the register without taking out your wallet. Most watches have payment built-in. You’ll just need to add your credit card before you start shopping.
  • With limited screen space, voice control is essential in a smartwatch. Consider the importance of voice control to you when making your smartwatch decision, as not all are equipped with this functionality.
  • Previously, active smartwatch wearers were disappointed that they couldn’t track their activity while swimming. Newer watch models correct that, but you’ll need to keep an eye on their limits. Some brands are designed to be submerged in up to 1.5 meters for only 30 minutes or less. Others are limited to up to 50 meters with no time constraint.
  • No matter which band you choose, you’ll still have to charge it at least every few days. Some watches use a magnetic charging cable that’s easy to connect. Others use a charging dock that you rest your watch on when you’re ready to charge.
  • Sleep tracking can provide valuable information, and some watches excels in this area. Some watches show how long you slept, as well as how many hours you spent in light, deep and REM sleep.
  • When you’re tracking your heart rate and sleep, you likely don’t want to be without your watch for long. Some watches take up to two hours to charge to 100 percent, while others are just over that at 127 minutes.
  • The band is an important part of the look and feel of your watch. Each smartwatch comes with a similar-looking plain black band. But there’s no shortage of bands available for purchase for each watch type, both from the manufacturer and third-party resellers. Look around at your options before you make a decision.
  • If you plan to stream music from your watch, some brands of watches will make that easier than others.
  • Though smartwatches can range widely in price, you’re sure to find a model that fits your specific needs and your budget.
