Released–July 2019
Measuring
TypeUpper armUpper arm
Clinically validated–Yes
Irregular heartbeat detectionYesNo
AFib detection or ECGYesYes
MethodAutomatic oscillometric upper-arm measurement during inflation. UK item 65400, EAN 4211125654009; manual type BM 64. Announced on 12 November 2023 with planned German availability from March 2024; actual first-sale date unresolvedCuff oscillometric; automatic inflation at 15 mmHg/s
AccuracyManual display accuracy ±3 mmHg for systolic and diastolic pressure and ±5% for pulse. Systolic range 50–280 mmHg, diastolic 30–200 mmHg and pulse 40–199 beats/minute; maximum cuff pressure 300 mmHg is separate±3 mmHg or 2% of reading (pressure), ±5% of reading (pulse); pressure range 0 to 285 mmHg; heart rate 40 to 180 bpm
Clinical validationCurrent manual claims clinical testing to ISO 81060-2; independent validation for this exact model not established. The shared launch release's pregnancy-validation claim belongs to BM 53, not BM 64Listed as validated by STRIDE BP (as BPM Core WPM04); Withings's study to ISO 81060-2:2018/AMD 1:2020, mean error −0.6 mmHg systolic, 0.1 mmHg diastolic
FeaturesAdvanced arrhythmia detection flags possible atrial fibrillation, without recording an ECG. Coloured classification scale, cuff-position check, HSD resting indicator and low-battery indication. Maker retains triple-measurement mode; May 2024 instructions describe three measurements with 30-second waits and a final average, while September 2026 instructions omit that operation sectionSingle-lead ECG with AFib detection (92% sensitivity, 98.4% specificity, Withings); digital stethoscope for valvular heart disease; colour-coded result
