Fitbit - Sense 2 smartwatch Shadow Grey/Graphite

Fitbit Sense 2 – Health tracking on a new level

Fitbit Sense 2 Shadow Grey/Graphite is a smartwatch designed to feel like a natural, comfortable extension of your wrist. Its slim and streamlined shape with newly raised band attachments makes it easier to wear from morning to night. The soft, nature-inspired color palette is perfectly in tune with current style trends. The vibrant AMOLED color display ensures readability wherever you go – choose from hundreds of watch faces and save up to five favorites directly to the watch. You can even personalize your device with a custom watch face using your own photo. When your phone is nearby, you'll receive call, text, and app notifications – and you can answer Bluetooth calls, send them to voicemail, and adjust the volume directly from your wrist.

Sense 2 helps you manage stress, sleep better, and includes advanced fitness tracking and smart features – plus a 6-month Fitbit Premium membership. With long battery life, it tracks your health and fitness data for over 6 days without recharging. A quick 12-minute charge powers it for a whole day. Water-resistant up to 50 meters, it's safe to wear in the rain, at the beach, or anywhere else your day takes you.

Exercise modes and activity

Sense 2 includes over 40 exercise modes – track your favorite activities like running, cycling, strength training, and yoga, with real-time metrics right on your wrist. Built-in GPS lets you see pace and distance without needing your phone. Start your morning with readiness insights and personalized workout suggestions. Real-time heart rate tracking ensures maximum benefit from your effort. The Active Zone Minutes feature guides you to your target intensity and helps maintain it. It tracks your activity all day, including steps, distance, floors climbed, calories burned, and Active Zone Minutes. Sweat it out with workouts from Fitbit coaches and partners in the app, and SmartTrack automatically recognizes your exercise and logs it post-workout. You can also assess your fitness level with VO2 Max – a measure of how efficiently your body uses oxygen during exercise. With Sense 2, you’ll elevate your workouts to the next level!

Health and wellness

Fitbit Sense 2 is designed to understand your body and encourage healthy habits. The SpO2 monitor shows how well oxygen circulates in your blood and may help detect changes in your wellbeing. Resting heart rate is a key indicator of cardiovascular health and fitness – and the app alerts you if it deviates from your normal range. You can also track heart rate variability (HRV) and use the skin temperature sensor to detect wellness changes such as illness onset. Log key health symptoms and, for women, track menstrual cycles and estimate ovulation. The new cEDA sensor continuously measures changes in electrodermal activity, helping you detect signs of stress or effects of caffeine. You’ll gain insights into when and why you feel stressed.

Improve your sleep with Sense 2. Monitor your sleep stages – light, deep, and REM – each night. Use sleep mode to keep the screen dark, and set smart vibration alarms to wake you during the ideal sleep phase for a more refreshed morning. Your personalized Sleep Score summarizes nightly sleep quality. Wake up refreshed with Smart Wake, which gently wakes you up within 30 minutes of your set time, during the optimal sleep phase. You can also use standard alarms. Sleep Mode mutes notifications and prevents the screen from lighting up during the night.

Smart features

Receive call, text, calendar, and app alerts (including Gmail and WhatsApp) directly on your watch. You can reply with quick messages or voice responses when your phone is nearby. Built-in Amazon Alexa lets you check the news and weather, set alarms, and get bedtime reminders using voice commands. Do Not Disturb mode silences all call, text, calendar, and app notifications during the day. The always-on display mode shows workout stats and time at a glance – even when your hands are full – and can be turned off to save battery. Find My Phone helps locate your missing device using a built-in alert: tap to trigger sound and vibration until it's found (requires the Fitbit mobile app to be active on your phone).

Fitbit Premium benefits

With the purchase of Fitbit Sense 2, you receive a 6-month Fitbit Premium membership. Enjoy thousands of expert-led workouts – from HIIT and cycling to dance sessions. Daily Readiness Score and stress insights help you better understand your body. The Health Metrics Dashboard reveals long-term health trends, while the Sleep Profile tells you whether your sleep patterns resemble a bear, tortoise, or another fun animal avatar – and offers tailored tips to improve your rest.
