Fitbit Sense 2 Advanced Health & Fitness GPS Smartwatch Graphite. All original contents are included. Charging Cable, LG/SM Bands, Manual & Inserts. The original box had damage, so we have substituted it with another similar Fitbit inner box. No outer box sleeve is included. On open box items we power up the unit and test for functionality. We install any firmware updates and then do a factory reset. Images 1-2 are stock photos for display purposes. Recognize stressful events, manage them and move on with our new continuous EDA sensor on Sense 2. It helps detect stress events so you can start to see how and when your stress is triggered. Use of the CEDA sensor may affect battery life. Get a handle on your stress. You’re showing fewer signs of stress. Time to find better balance–try a meditation or go for a walk. It’s easier to get better sleep when you know what kind of sleeper you are. Find out whether your sleep mirrors a deep-sleep bear, a slow-to-sleep tortoise or one of our other Sleep Animals. Then learn what habits best to support your profile. Sleep Stages & Sleep Score. Learn about the quality of your previous night’s sleep with a personalized Sleep Score. With Premium, see a breakdown of time in light, deep & REM sleep to see what’s impacting your rest. Fitbit ECG App & Irregular Heart Rhythm Notifications. There are two ways to uncover Afib, right at your fingertips. With the ECG app, you can take an assessment on demand. Plus, use irregular heart rhythm notifications to look for signs of Afib while you’re still or sleeping. High & Low Heart Rate Notifications.

Enhance your workout routine with a Daily Readiness score that reveals if you’re ready to push or should focus on recovery. Get the results you want from every workout.
