FAQ

What makes ScanWatch Nova Brilliant a meaningful investment?

ScanWatch Nova Brilliant is more than just technology; it is a clinical-grade instrument integrated into a high-end timepiece. Built with premium materials like sapphire glass and mirror-finish stainless steel, it houses advanced sensors dedicated to your heart health. It represents a rare bridge between luxury watchmaking and medical science, engineered to support your health for years to come.

Is this a smartwatch or a medical device?

It is a high-performance hybrid. ScanWatch Nova Brilliant combines the aesthetics of a luxury watch with the precision of a clinically validated medical device. Beyond activity tracking, it detects subtle physiological changes before you even notice them. It is a reliable health tool designed to monitor your well-being with precision and sophistication.

Can I respond to messages or use built-in GPS on my watch?

ScanWatch Nova Brilliant is designed for focus and a 35-day battery life. While you cannot respond to messages directly or use built-in GPS, you can read notifications at a glance and map your outdoor routes by pairing with your smartphone’s GPS. This minimalist approach allows for continuous health monitoring without the distraction of digital clutter.

Do I need a subscription to access my health data?

No. Access to your baseline metrics and trends remains free within the Withings app. Withings+ is an optional premium service that provides deeper analysis and expert-led guidance to help you optimize your health trajectory. An introductory one-month trial is available when you select the subscription option at purchase, allowing for a full evaluation before billing begins. View subscription details here.

¹ScanWatch Nova Brilliant incorporates the medical device software Withings ECG App. Withings ECG App enables the detection of atrial fibrillation through ECG readings. The ECG functionality has been cleared by the FDA. Please read the user instructions carefully. If you have any concerns about your results, consult your doctor. (08/08/2025)

²Temperature tracking is designed to indicate deviations from your typical temperature pattern and is not a medical thermometer. Temperature data should not be used to detect fever, or to diagnose, treat, cure, or prevent any disease. For accurate measurements or in case of symptoms, use a clinical thermometer and always consult a healthcare professional.

³The predicted fertility window and retrospective ovulation confirmation provided are for informational purposes only and are not medical features. It should not be used for the control or support of conception. Always consult a healthcare professional for fertility or reproductive health guidance.

4 The ECG and irregular heart rhythm notification features have not been tested and are not intended for use in people with cardiac pacemaker, implantable cardiac-defibrillator, or other implanted electronic device.
