But smartwatches have the innovation advantage these days as most companies making such devices try to develop features that competitors don't have. As a result, fitness trackers have become a bit stale. And after wearing the new Charge 3 for nearly two weeks to see how well Fitbit's gentle marriage of smartwatch and tracker features turned out, it seems the form factor remains radically unchanged—but that's not a bad thing in practice.

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.
Like other Fitbit devices, the Charge 3 takes little effort to set up. It works with Android and iOS devices, and all you need is the Fitbit mobile app to use it. Choose the Charge 3 from the list of devices you can pair via Bluetooth to your smartphone or tablet, and follow the on-screen instructions. After setup, you may want to also edit basic information that the Charge 3 uses when tracking activity, such as your age, height, weight, and the activity metric you care most about (steps, active minutes, etc).
In 2003, Fossil released the Wrist PDA, a watch which ran the Palm OS and contained 8 MB of RAM and 4 MB of flash memory. It contained a built in stylus to help use the tiny monochrome display, which had a resolution of 160×160 pixels. Although many reviewers declared the watch revolutionary, it was criticized for its weight (108 grams) and was ultimately discontinued in 2005.
I've been pleased to see swim-tracking trickle down into more affordable devices over the past few years. Fitbit's Flex 2 remains its most affordable device with swim-tracking features, priced at $60. But the $150 Charge 3, with its big display and smattering of smartwatch capabilities, is for a different audience than those who would gravitate to the tiny, quasi-cylindrical Flex 2. Even if you don't swim often, water-resistance up to 50 meters means users don't have to worry about showering with the Charge 3 or dropping it in the pool by accident.
