You can choose from five different watch faces for the Charge 3, making it less customizable than the Ionic or the Versa. Those smartwatches have the advantage of running Fitbit OS, which includes a library of many third-party-developed watch faces. The Charge 3 isn't a smartwatch, so its version of Fitbit's software isn't as robust as what we see on the Ionic and the Versa. It's not as critical for the Charge 3 since it isn't designed to run more than a few basic apps, but those looking for interesting watch faces will have to do with just a handful of options.
As for the tech inside, the Q Venture won't let you down. It runs WearOS (previously known as Android Wear) and works with thousands of apps on the Google Play Store. You can answer texts, interact with notifications, and choose your own watch face — just like you would on any other smartwatch. Fossil has lots of nice watch faces in feminine colors, too.
Some smartwatches have robust offerings of apps, either preinstalled on the watch or available for download in an app store. Apps can be as simple as a timer or stopwatch, or can control your smart-home devices, switch up your music, or provide turn-by-turn directions for walking or driving. In our testing and everyday use, however, these watch apps rarely offer a great experience. But there are some exceptions, including some fitness apps and apps that track things like water or food intake.
For instance, I rarely use the touchscreen on my Fitbit Versa because the shortcuts to my most-used smartwatch features are available via the three physical buttons on the watch. Gesture recognition is hit and miss on smartphone screens, nowhere near as responsive and accurate as on your smartphone screen, so bear that in mind too. Force Touch is a useful feature that has come to smartwatches, notably the Apple Watch. Just press down or tap the screen to activate different features.
How frustrating. I really -like- the idea of a smart watch... but it's so hard to find the right one. I'm not an exercise freak so heartrate monitors etc are useless to me. I really like the design of the Samsung watches with their bezels to control it, but the Tizen OS with it's limited apps puts me right off. The Access Grayson watch is beautiful, but the lack of NFC is a deal breaker for me - Google Pay with the convenience of a watch is part of the reason I'd buy one. I don't need to be able to put a sim in it... that's what my phone's for, but GOS would be nice for when I travel, and as a motorbike rider some level of waterproofing is a must. Guess I'm waiting for the next round of watches to see what's on offer.
Aside from its jack-of-all-fitness-trades, master-of-none nature, the Gear Sport has other drawbacks. Chief among them is that voice dictation is significantly less reliable than on the Apple Watch or Wear OS and is best used for short phrases and quick replies. Then there’s S Voice, the digital assistant that can’t do much—and you probably don’t have time to learn how to make it do the few things it can do. And major apps still do not have a presence in Samsung’s marketplace—the Sport runs Samsung’s Tizen operating system instead of Wear OS—so any app or device you want to control directly on your phone is a gamble on an indie developer having the same need.
The RC-1000 Wrist Terminal was the first Seiko model to interface with a computer, and was released in 1984. It was developed by Seiko Epson and was powered by a computer on a chip. It was compatible with most of the popular PCs of that time, including Apple II, II+ and IIe, the Commodore 64, IBM PC, NEC 8201, Tandy Color Computer, Model 1000, 1200, 2000 and TRS-80 Model I, III, 4 and 4p. The RC-20 Wrist Computer was released in 1985, under the joint brand name "Seiko Epson". It had a SMC84C00 8-bit Z-80 microprocessor; 8 KB of ROM and 2 KB of RAM. It had applications for scheduling, memos, and world time and a four-function calculator app. The dot-matrix LCD displayed 42×32 pixels, and more importantly, was touch-sensitive. Like the RC-1000, it could be connected to a personal computer, in this case through a proprietary cable. It was also notable in that it could be programmed, although its small display and limited storage severely limited application development. The RC-4000 PC Data graph also released in 1985, was dubbed the "world's smallest computer terminal". It had 2 KB of storage. The RC-4500 (1985), also known as the Wrist Mac, had the same features as the RC-4000, but came in a variety of bright, flashy colors.
The top smartwatches that debuted at the 2017 Consumer Electronics Show included the Casio WSD-F20, Misfit Wearables Vapor and the Garmin Fenix 5 series. Apple released on September 22, 2017 their Apple Watch Series 3 model which offers built in LTE cellular connectivity allowing phone calls, messaging and data without relying on a nearby smartphone connection. 
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.
If you’re into premium smartwatches, the Montblanc Summit is the latest option hitting watch shops around the world. Out of the box, it runs atop Android Wear 2.0 with the standard specifications — Snapdragon Wear 2100, 512mb of RAM, and 4GB of storage. There’s no NFC or LTE on board, but the watch does feature a heart rate sensor and premium materials.
If you’d prefer your smartwatch looked more like a piece of jewelry than a small computer on your wrist, you’ll like Skagen’s Falster range. The straps of these slimline watches come in a few different leather or stainless steel options but coupled with the included minimalist watch face designs, they all look sleek and stylish in a way few other smartwatches manage.
Samsung’s Gear Sport is not as stylish as Fossil’s Q watches, and because it runs Samsung’s Tizen operating system instead of Wear OS, it has nowhere near the app support of Wear OS. But as a smartwatch that shows your phone notifications and lets you respond to them, lasts all day, and tracks your recreational workouts, it is a great device. It’s not meant for competitive speed training, but it has built-in GPS and heart-rate sensing, offline Spotify storage, and a rotating bezel that’s much easier to use while exercising than a touchscreen. It does suffer from weak voice transcription and a barely-there S Voice “assistant,” but it fits a lot of core smartwatch functions into a relatively smart-looking package that’s better for fitness-minded wearers than our top picks.
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.
