Measuring
Type
Type	Wrist	Wrist
Irregular heartbeat detection
Irregular heartbeat detection	Yes	Yes
AFib detection or ECG
AFib detection or ECG	No	No
Method
Method	Automatic oscillometric wrist measurement during deflation. Exact UK item 65046, EAN 4211125650469; SK2 voice-language version. First-sale date unconfirmed	Automatic oscillometric wrist measurement; exact manual describes inflation followed by gradual pressure reduction. No Comfort+ inflation-measurement claim transferred from W3 Comfort. Manufacturer labels it new 2025/26, but exact first-sale date remains unresolved
Accuracy
Accuracy	Exact manual display accuracy ±3 mmHg for systolic and diastolic pressure and ±5% for pulse. Systolic range 60–260 mmHg, diastolic 40–199 mmHg and pulse 40–180 beats/minute; cuff-pressure range 0–300 mmHg is separate	Static pressure accuracy ±3 mmHg and pulse ±5% of readout. Systolic 60–255 mmHg, diastolic 40–200 mmHg and pulse 40–199 bpm in current manual; website rounds pulse upper limit to 200. Cuff-pressure display range 0–299 mmHg is separate
Clinical validation
Clinical validation	Exact manual gives an unspecified clinical-test maximum permissible standard deviation of 8 mmHg, without identifying a published study. Medaval reports no peer-reviewed clinical validation information for BC 21, but incorrectly labels its measurement site upper arm; exact maker manual establishes wrist measurement. Independently established headline validation omitted	Manufacturer product page claims ISO clinical validation and manual claims ESH testing; no exact-model independent validation listing or published trial recovered in bounded searches. Headline validation omitted pending independent evidence
Features
Features	Spoken instructions and results in German, English, French, Italian or Turkish for UK item 65046; three volume levels or off. Shared data sheet separately lists item 65040 with English, Spanish, Polish, Arabic and Farsi; those languages are not part of this UK version. Irregular-heartbeat warning, coloured classification scale, date/time, application-error messages and automatic switch-off. No dedicated AFib screening, ECG, movement detection, heart-level position or resting indicator	Ordinary irregular-heartbeat indication, cuff-fit check, arm-movement warning, blood-pressure classification display, low-battery indicator and automatic switch-off after approximately one minute. Website mentions an LED positioning indicator, but exact manual labels a traffic-light display and establishes no separate heart-level positioning sensor; claim remains unresolved. No dedicated AFib algorithm or MAM sequence established
Cuff
Cuff fits
Cuff fits	14–19.5 cm	13.5–21.5 cm
Cuff
Cuff	Attached wrist cuff for 14–19.5 cm circumference. User must position the cuff at heart level; no electronic position guidance	Pre-formed wrist cuff fits 13.5–21.5 cm; damp cloth and mild soapsuds for cleaning, no machine washing

Memory
Memory	Two users with 60 dated readings each; oldest overwritten when full. Average of all stored values and morning (05:00–09:00) or evening (18:00–20:00) readings over the latest seven days. Deletion clears the selected user's entire memory	Stores 30 readings with date/time and displays average of all stored values, excluding readings with suboptimal cuff fit. Oldest reading overwritten when full. Current exact manual explicitly says removing batteries deletes stored measurements; no memory retention borrowed from W1 Basic or W3 Comfort. New reading can be excluded; saved history clears together. No separate user selector established
App
App	No Bluetooth or connection from the monitor. Current Scan & Save support captures displayed values using a smartphone camera into beurer HealthManager Pro; not automatic transfer	–
Power
Power	Two 1.5 V LR03 AAA alkaline batteries; approximately 200 measurements depending on blood pressure and inflation pressure. Battery operation only	Two 1.5 V AAA alkaline batteries; approximately 700 measurements with new cells. NiMH rechargeable cells supported but charged externally. Product page and manual agree on two cells; support table incorrectly gives four
Design
Display details
Display details	Non-illuminated LCD with black digits, maker size 3.8 × 4.5 cm. Physical membrane memory and start/stop controls; low-battery indicator. Manual IP22	LCD with ON/OFF, memory and time controls plus separate classification display; IP22 in current exact manual
Size
Size	Exact manual and September 2021 data sheet give 87 × 67 × 31 mm (L × W × H) and approximately 105 g without batteries; data sheet specifies cuff included. Current product table instead gives 87 × 67 × 70 mm and 187 g excluding packaging, with weighing conditions unspecified; differences unresolved	Exact operating manual gives 76 × 67 × 29 mm and 127 g including batteries. European product/support tables instead give 131 × 90 × 60.5 mm; larger figures are not adopted as body dimensions or guessed to be packaging
In the box
In the box	Monitor with attached cuff, two AAA batteries, storage box and instructions. Current product page also lists a blood pressure record	Monitor, storage box, two AAA alkaline batteries and blood-pressure diary listed by manufacturer; operating instructions available
