The problem is that to monitor your sleeping patterns, a valuable feature most of these new smartwatches support, the watch needs to be on your wrist. So leaving your watch charging overnight while you slumber isn’t going to work. But smartwatches have small batteries compared to smartphones, so should only take 2 - 4 hours to fully charge, depending on the model.
We've just completed lab tests on six of the newest smartwatches to hit the market. Three run on the very promising Android Wear operating system, which Google created specifically for wearable devices—the LG G Watch, Samsung Gear Live, and Motorola Moto 360. We also tested several basic models: the Martian Notifier, Cookoo 2, and MetaWatch M1. And we included reviews of nine smartwatches that we tested previously; all are still available, and we updated their prices. Find out what we liked and didn't like about the six newly tested models.
Why we like it: Compared with a smartwatch or fitness tracker, a dedicated GPS running watch is focused on one category of exercise: outdoor movement. GPS watches offer the fastest GPS signal lock-on and more-precise maps, while also showing up to the second details on your pace, heart rate, mile split times, and a host of other stats on an always-on display. The physical buttons on a GPS watch are easier to use while moving (and without looking), rather than having to swipe or tap on a tiny glass screen. A GPS watch’s longer battery life can better handle endurance events than a smartwatch. And the software and apps behind a good GPS watch provide more statistics and training programs to improve your efficiency. While GPS watches can show notifications, the weather, and a few other smartwatch-like conveniences, they’re much more limited in what can be done from a wrist than a smartwatch—or even a fitness tracker like the Vívosmart.
As far as the number of sports available to track: while it's more of the same, there are some notable exclusions - like golf tracking and open water swimming (pool swimming is a there though). Heart rate monitoring is decent if not class-leading, and it won't keep you waiting around for a GPS signal. There's also all the stress tracking goodies from Garmin's fitness trackers, too. As multi-sport smartwatches go, this is the best in our eyes, and builds on all the good work Garmin did with its previous iterations.
They include a heart rate monitor, pedometer and altimeter to track steps taken and stairs climbed and often a GPS chip to record your distance covered. They will sync with your smartphone to give you a suite of tools to monitor your exercise progress. Many of them will offer notifications of incoming phone calls, text and email alerts as well. But they are designed with fitness tracking in mind. If you are happy using your smartphone for your day to day messaging, calendar, apps and music, a fitness tracker will suffice.
Like previous Gear watches, the Gear Sport uses a rotating bezel and two side buttons for most of its navigation. This works better than you’d think by looking at it, and it’s a boon to those who wear gloves for part of the year. In fact, we actually prefer this approach to Wear OS or the Apple Watch: Rotating through your home screens, notifications, lists of apps, or messages happens at remarkable speed for a tiny device. The screen is 1.2 inches and 360 pixels in diameter, but it’s brighter than our pick’s, and it looks decent enough while displaying most content, though text isn’t as sharp as on the Fossil screens. The watch itself is not small, at 43 and 44 millimeters wide and tall, respectively, and 11.6 mm thick, but it’s nowhere near as beefy as our prior pick, the Gear S3.
The Apple Watch Series 4 is now on sale, and it's the best smartwatch you can buy right now. The redesigned device, which starts at $399 for the GPS model and $499 for the cellular version, is the best smartwatch you can buy. It has a larger display and slightly bigger case size while retaining the same rounded square design the watch is known for. Even more importantly, Apple received FDA clearance for a new electrocardiogram feature that can take a 30-second EKG and diagnose atrial fibrillation.
