What owners single out
In their words
“Been wearing this watch for a month and love it!! This is the watch you want! The Withings Scanwatch is the do it all smartwatch. Style meets functionality. Packed with features to monitor your health, like on demand ECG, oxygen saturation level, breathing disturbances, proactive heart rate tracking and is the first Withings watch to be FDA cleared for its oximetry and ECG features.”

“I received this watch in black and I’m really loving its timeless sleek look. It’s versatile and fits beautifully with all daily looks, from casual to business attire. It was a treat to unbox it and discover the lovely felt pouch it was wrapped in. Little tab pockets inside the pouch held the charger and additional accessories. The watch is fairly lightweight and feels great on my wrist.”
