The Fitbit Versa is a prettier, cheaper version of the company's first true smartwatch, the Ionic. It lacks built-in GPS and NFC payments, but you'll save $100 if you opt for the new watch over the original. Fitbit promises you'll get "four-plus" days out of its battery, and, indeed, the watch only conked out after close to five days of use, during which it tracked at least two workouts and four nights of sleep.
