    Product Specifications

    Sleep Experience

    Improve sleep quality, increase your energy and better manage stress with help from Sense 2 + Premium. Track your sleep each night to see how much time you spent in deep, light and REM sleep. Then check your Sleep Profile – a report that breaks down your sleep patterns and trends over the past 30 days plus provides personalised guidance for better rest. You can even programme your display to stay dark at night and set gently buzzing morning alarms that wake you up during the ideal sleep stage for a refreshing morning rise.*

    Sleep Profile (Premium)

    Learn your sleeping style with a monthly breakdown of 10 key sleep metrics. You’ll see which of the 6 distinct Sleep Animals your sleep compares to and what you can do to get better rest.


    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 support your profile.

    Sleep Stages and Sleep Score

    Learn about the quality of your previous night’s sleep with a personalised Sleep Score. With Premium, see a breakdown of time in light, deep and REM sleep to see what’s impacting your rest.

    Smart Wake

    Stress Experience (Validation in Progress)

    Understand your stress, then minimise its effects

    Managing stress can lead to better sleep, improved mood and more energy. Sense 2 + Premium are here to lend a hand. Together they can help you better understand and respond to stress so you are less affected by it over time. Sense 2 is the first watch [[CLAIM VALIDATION IN PROCESS]] to use a continuous EDA sensor to detect stress events so you can pinpoint patterns of stress in your life and learn to proactively manage them with recommendations for mindfulness, breathing, exercise and more.*

    All-Day Body-Response Tracking

    Using a cEDA sensor, identify signs of stress, excitement, effects from caffeine and more. Over time you’ll be able to recognise your stress triggers and manage it in the moment. Use of the cEDA sensor may affect battery life.
