The Advanced Fitbit Watch

This is the fitness watch that tracks your exercise, heart rate, and sleep cycles, while also providing coaching, GPS functionality, and multiple sports modes. It has an accelerometer that monitors the intensity and duration of movements as well as records steps taken, distance traveled, and calories burned. The device also has an altimeter that measures elevation and a built-in ECG that measures heart rate. As comfortable and unobtrusive as a gel wristband, the Fitbit watch tracks tiny tremors in the wrist to determine how long you took to fall asleep, how often you woke up, time spent in REM, and the level of sleep quality. It provides personal fitness coaching with on-screen guidance, GPS tracking, and modes to monitor specific workouts in real time. Statistics are synced wirelessly to an app compatible with Android, Apple iOS, and Windows devices. The wearer also has the option to set alarms, store and play up to 300 songs, and receive smart notifications. Made of elastomer with surgical-grade stainless-steel frame, the device is sweat-and-water resistant. Includes small and large wristbands to fit most wrists. Charges via USB; a full charge provides up to four days of power. Charcoal. Case 8 3/4" L x 4" W x 2" D. (10 oz.)
