Pebble (watch) was an innovative smartwatch that raised the most money at the time on Kickstarter reaching $10.3 Million between April 12 and May 18, 2012. The watch has a 32-millimetre (1.26 in) 144 × 168 pixel black and white memory LCD using an ultra low-power "transflective LCD" manufactured by Sharp with a backlight, a vibrating motor, a magnetometer, ambient light sensors, and a three-axis accelerometer.[47][48][49][50][51] It can communicate with an Android or iOS device using both Bluetooth 2.1 and Bluetooth 4.0 (Bluetooth Low Energy) using Stonestreet One's Bluetopia+MFi software stack.[52] Bluetooth 4.0 with low energy (LE) support was not initially enabled, but a firmware update in November 2013 enabled it.[53] The watch is charged using a modified USB-cable that attaches magnetically to the watch to maintain water resistance capability.[49] The battery was reported in April 2012 to last seven days.[54] Based on feedback from Kickstarter backers, the developers added water-resistance to the list of features.[55] The Pebble has a waterproof rating of 5 atm, which means it can be submerged down to 40 metres (130 ft) and has been tested in both fresh and salt water, allowing one to shower, dive or swim while wearing the watch.[56]
Software may include digital maps, schedulers and personal organizers, calculators, and various kinds of watch faces. The watch may communicate with external devices such as sensors, wireless headsets, or a heads-up display. Like other computers, a smartwatch may collect information from internal or external sensors and it may control, or retrieve data from, other instruments or computers. It may support wireless technologies like Bluetooth, Wi-Fi, and GPS. For many purposes, a "watch computer" serves as a front end for a remote system such as a smartphone, communicating with the smartphone using various wireless technologies. Smartwatches are advancing, especially their design, battery capacity, and health-related applications.[5]
Out of a vast field of similar watches, we picked the Q Explorist and Q Venture because of their middle-of-the-road prices, wide availability, and variety of styles. These two models are flagships for the Fossil Group’s collection of 14 style brands producing more than 300 planned smartwatches. This means that if you find a smartwatch from Diesel, Skagen, Tag Heuer, Kate Spade, Movado, or another Fossil-connected brand that fits your style better, you should feel free to buy it, because it will have roughly the same internal hardware as our picks.

Flaws but not dealbreakers: The Vívosport’s screen is highly sensitive to incidental brushes and touches; we ended up activating the screen auto-lock feature, a small annoyance. Compared with a dedicated GPS running watch, the GPS tracking on any fitness band takes longer to connect to satellites; and it’s easier to see your pace and other statistics on a running watch’s larger LCD screen while moving than on a fitness band’s relatively miniscule display. Garmin doesn’t have the motivating social network of Fitbit, so it’s less likely that your friends or coworkers will connect and challenge you, or that a corporate fitness challenge will work with your Vívosport. A fitness band falls short of a full-featured smartwatch, because typically it won’t give you a voice assistant, let you install apps, or let you interact with phone notifications, and many of those notifications will be difficult to read on the Vívosport’s small screen.

Fitbit Versa: The Fitbit is the health tracker for the masses and they have a model for every need. But the best option for adults who do a moderate amount of exercise and just want to keep tabs on their general fitness (ie: most of us), the Fitbit Versa is a great choice. It's an entry-level smartwatch. For more on the Fitbit Versa’s various attributes, read my in-depth review. ($350)
Although rectangular is the most common design, there are smart watches that have a circular display similar to regular watches. The Apple Watch is only available in the rectangular design. The circular design is available in the Samsung Gear S2, Moto 360, and LG G Watch R models. Many models have changeable straps, so you can dress casual, sporty, and formal.
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.
Having a miniature computer strapped around your wrist is no longer a pipe dream. The Apple Watch and other options from popular manufacturers, like Fitbit, Samsung, LG, and Fossil, have been gunning to craft the best smartwatch. Now a few years more mature, the smartwatch market offers more than ever, whether you’re after a particular style, iOS and Android phone compatibility, or just a bunch of features.

Our top pick for most people is the Apple Watch Series 4 with GPS (starting at $399), which has a huge display, ultra-fast processor, Raise to Speak Siri, fall detection and a built-in electrical heart rate sensor for taking on-the-go electrocardiograms. It also runs watchOS 5, which makes the watch even more useful with automatic workout-tracking, offline podcast playback and a Walkie-Talkie voice chat feature.
