The Withings ScanWatch (the ScanWatch 2 at about $349 and the ScanWatch Nova, including the Nova Brilliant at about $600, November 2024; from Withings, founded 2008 in France and independent since buying itself back from Nokia in 2018) is the hybrid-analog entry of the biometric cohort: a conventional analog watch dial paired with medical sensors (optical PPG, electrical ECG, SpO2, and TempTech24/7 continuous temperature) and about 30-day battery. Its cleared features include ECG (for AFib, sinus rhythm, and high heart rate, cleared 2021, with an OTC ECG clearance in 2025), SpO2 with breathing-disturbance detection, and temperature trends, with an optional Withings+ subscription (~$9.95/month). It carries substantial peer-reviewed cardiologist validation for the size of the company. Cap-flag: as a French maker it is cleared in both the EU and the US, with different specific indications by region.

Specs

notes
  • FDA clearances: ECG app: FDA-cleared Oct 2021 (single-channel; classifies AFib/sinus rhythm/high HR; adults 22+). July 2025 update: ScanWatch 2 ECG cleared OTC - US users no longer need a board-certified cardiologist to activate ECG; new AFib algorithm gives 8 classifications (up from 4). SpO2: FDA-cleared (supports tracking blood-oxygen + breathing disturbances at night).
  • CAP-FLAG + clean contrast: 'Breathing disturbances detection' is a SCREENING AID, not a sleep-apnea DIAGNOSIS - framing it as apnea diagnosis exceeds scope. Clean contrast to Apple: Withings' SpO2/ECG were NEVER disabled in the US (not party to the Masimo dispute); the notable 2025 regulatory event was a POSITIVE OTC liberalization, not a restriction.
  • Verification posture: Boundary: biometric-primary + AI-augmented. Clinical posture: SUBSTANTIAL-for-size (strong clinical-study framing; multiple ScanWatch SpO2/apnea validation studies; CE medical marking). NOT verified: exact K-numbers/dates for ScanWatch 2 SpO2 + temperature clearances (K240795/K240909 seen but date-to-feature mapping not fully nailed); standard ScanWatch Nova + ScanWatch 2 US list prices (approximate).
