Withings - WITHINGS Steel HR Sport Smart Watch White Hybrid Smartwatch

Watch your health
Keep on top of your personal goals day and night with the hybrid smartwatch that delivers a detailed overview right to the companion app.

24/7 heart rate monitoring
With its 25 days of battery life, Steel HR takes readings around the clock to give a holistic view of your heart. Enjoy heart rate tracking day & night plus continuous tracking during workouts.

Why it matters
In most cases, a lower heart rate is the result of better cardiovascular fitness. Track the evolution of your heart rate over time and use it to improve overall health.

What’s behind the tech
Steel HR collects data on heart rate using photoplethysmography (PPG). Unlike other trackers, the HR sensor is protected by a scratch-proof sapphire glass to ensure accurate measurements over the long term. In order to optimize energy consumption, Steel HR will monitor heart rate at a varying frequency, according to your real-time activity.

Daily activity tracking
Steel HR automatically counts steps and recognizes walking, running, swimming or sleeping. Steel HR is water-resistant to 50m.

Sport monitoring
Easily activate workout mode right on your wrist by choosing from over 30 sports. This will activate a timer, continuous heart rate connected GPS. Open your Withings App after your workout to get duration, distance, and your path map.

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.

Sleep score
Every day, find out how restorative the night was with a score based on duration, depth, regularity & interruptions.

In-depth reporting
Open the Withings app to view light and deep sleep stages plus overnight heart rate.

Connected GPS
If it is relevant to your type of workout, Steel HR leverages the GPS of your phone to offer a precise map of your path.

Fitness Level assessment
Steel HR Sport can assess your Fitness Level when you run or walk based on the maximal oxygen consumption (VO2 Max) estimation.

A key indicator of fitness
VO2 max is defined as the maximum amount of oxygen an individual consumes over one minute during intense physical effort. The more oxygen consumed, the harder muscles can work, and therefore the higher the VO2 max level.

What’s behind the tech
The algorithm to calculate VO2 max has been developed by Firstbeat, a company which is the reference on the market. It is proven to be 95% accurate compared to laboratory measurements.

Record battery life
With a rechargeable battery life of up to 25 days, you can spend more time moving and less time charging.

Smart notifications
You can stay in-the-know on the go with a vibration and smartphone notifications right on the embedded digital screen. Steel HR supports calls, texts, events and all the apps you choose.
