Measuring

Type
Wrist
Clinically validated
Yes
Irregular heartbeat detection
Yes
AFib detection or ECG
No
Method
Automatic oscillometric wrist measurement during inflation with Comfort+; exact current European manual identifies BP3KB1-3E. First on-sale date unresolved
Accuracy
Static pressure accuracy ±3 mmHg and pulse ±5% of readout. Current European manual gives systolic 60–255 mmHg, diastolic 40–200 mmHg and pulse 40–199 bpm; older UK manual gives 20–280 mmHg blood pressure and 40–200 bpm. Cuff-pressure display 0–299 mmHg is separate
Clinical validation
STRIDE BP approves equivalence to W2 Slim, whose 2016 adult validation used ESH-IP 2010 and ANSI/AAMI/ISO 2013; not a separate published W3 Comfort trial. STRIDE lists a 13.5–23 cm cuff. Manufacturer BIHS A/A marketing and current manual ESH/ISO wording are retained as claims, not additional independent trials
Features
Ordinary irregular-heartbeat indication, cuff-fit check, arm-movement warning, single-colour blood-pressure classification scale, low-battery indicator and automatic switch-off after approximately one minute. No dedicated AFib algorithm, MAM sequence or electronic wrist-position sensor established

Connections and memory

Readings stored
30
Bluetooth and app
No
Memory
Stores 30 readings with date/time and displays average of all stored readings, excluding suboptimal cuff fit; not specifically the last three. Oldest overwritten when full. Readings retained on cell replacement, clock reset. New reading can be excluded; saved history clears together. Exact controls establish no separate user selector
Power
Two 1.5 V AAA alkaline cells; approximately 320 measurements with new cells. NiMH cells supported but must be removed and charged externally

Cuff

Cuff
UK product page and its EN-FR 4119 manual give 13.5–23 cm and a soft D-ring wrist cuff. European August 2026 manual instead gives 13.5–21.5 cm despite the European product page still advertising 23 cm. Headline cuff range omitted pending exact supplied revision confirmation; no inferred second hardware model

Design

Display details
LCD with ON/OFF, memory and time controls. Older UK manual gives IP20; current European August 2026 revision gives IP22. Revision conflict retained rather than assuming an upgrade applies to every unit
Size
81 × 65 × 21 mm; 112 g including batteries
In the box
Monitor, storage case, two AAA alkaline batteries, instructions and blood-pressure diary. Current range listing establishes catalogue presence, not worldwide stock or first-sale date
