- 2020 A medical tracker in disguise Presented in January 2020, the ScanWatch paired an ECG with continuous blood oxygen sensing, aimed at early signs of atrial fibrillation and sleep apnea.
- 2021 to 2022 Dressed as a diver On 29 September 2021 Withings added the ScanWatch Horizon, a 43 mm steel diver with a rotating bezel, sapphire glass and 10 ATM water resistance.
- 2023 Reading the skin's warmth At IFA in Berlin on 31 August 2023 came the ScanWatch 2, with a heat-flux sensor for skin temperature and cycle tracking, and the cheaper ScanWatch Light.

Presented in January 2020, the ScanWatch paired an ECG with continuous blood oxygen sensing, aimed at early signs of atrial fibrillation and sleep apnea. CEO Mathieu Letombe called it the company's most ambitious medical tracker; it sold in Europe from 38 mm at 279 euros while US clearance was pending.
