Withings Steel HR Hybrid Watch

#1 WORLDWIDE, WITHINGS INVENTED THE FIRST HYBRID SMARTWATCH If you wear Steel HR to bed it will automatically track light and deep sleep cycles, duration, and sleep quality via the Sleep Score. Plus, the Smart Wake-up feature can get you out of bed at the best time according to your sleep cycle. WHY IT MATTERS Sleep tracking helps you understand your night and make choices that can improve them. Studies have shown that better sleep helps people manage weight, reduce blood pressure, and even reduce the risk of cardiovascular events. WHAT’S BEHIND THE TECH The accelerometer, paired with heart rate, allows a comprehensive and detailed analysis of your night. Our proprietary AI has been calibrated with a sleep laboratory in Manheim, Germany and with Beclere Hospital in France, using polysomnography, considered to be the gold standard for sleep analysis.
