The Huawei Watch D3 and Whoop MG both get recommended to people who typed "blood pressure wearable" and stopped reading. One is a £399.99 watch with an inflatable cuff and 24-hour monitoring. The other is a screenless band you can only get by paying Whoop $359 a year, and its blood pressure feature is an estimate. They are not substitutes.

Quick verdict
Buy the Huawei Watch D3 if you want millimetres of mercury from a wrist cuff and you can buy it where that measurement is certified. Buy Whoop MG, which means Whoop Life at $359 a year, if you want a screenless training coach and you will treat blood pressure as a calibrated wellness trend. Do not buy either one as a substitute for a validated upper-arm monitor your clinician already uses.
They answer different questions
Both products show up in the same Google results because both say blood pressure. The hardware does not overlap. The Watch D3 inflates a mechanical airbag in the strap and reports systolic and diastolic pressure with the oscillometric method. Whoop MG estimates blood pressure insights from optical sensors after you calibrate it against an external cuff, and Whoop labels that output as a wellness feature, not a diagnostic device.
That split should end the shopping trip for a lot of people. If a GP has asked for numbers, the Whoop card is the wrong artefact. If you want to know whether to train today, the D3's cuff is a slow way to get a recovery score you could have had from Whoop 5.0 or a Garmin CIRQA. The full D3 walkthrough is in the Huawei Watch D3 review.
Side by side
| Huawei Watch D3 | Whoop MG (Life) | |
|---|---|---|
| Price | £399.99 once in the UK. About €449 in Europe. No official US price. | $359 a year. Hardware only comes with Life. About $1,077 over three years. |
| Blood pressure | Inflatable wrist cuff. Spot, 24-hour ABPM, and pre/post run, walk and cycle. | Cuffless insights. Needs an external cuff to calibrate. Wellness, not a medical device. |
| Screen | 1.92-inch AMOLED, 3,000 nits peak claim. | None. The phone is the display. |
| Battery | Up to 6 days typical. About 1 day with ABPM on. | About 14 days, charged on the wrist. |
| Training coach | 100-plus workout modes. Physical Readiness is a promised update. | Sleep, Strain and Recovery on every tier. Life adds Healthspan and the cardiac extras. |
| ECG | On-watch ECG in supported markets. Not a diagnosis. | On-demand ECG Heart Screener on Life, where cleared. |
| Water | Off for swimming and showers. | Worn through showers and most training. Check the current band rating before open water. |
| Best for | People who will sit for a cuff reading and share an ABPM report. | People who already live in Whoop's coaching and want the cardiac tier. |
Blood pressure, in practice
A D3 spot check is a minute you organise. Seated, feet flat, wrist at heart height, quiet, no pressure on the airbag. Ambulatory mode repeats that through the day and inflates on its own at night. Huawei points at European Society of Hypertension guidance: 15 to 30 minute intervals, 70 percent success, 20 daytime readings and 7 at night. The watch can generate a report in Huawei Health. Battery drops to about a day while that plan is running, which is acceptable for a study and annoying as a lifestyle.
Whoop's insight is the opposite shape. You wear the band continuously, you calibrate it with a real cuff, and the app later shows a trend. There is no inflation, no posture card and no 24-hour medical report. Our Whoop MG review treats it as an extra room inside Life, not as the reason most members should upgrade from Peak. Whoop's own framing matches that: estimated, calibrated, not a clinic tool.
Accuracy evidence on the D3 is early and mixed. T3's three comparisons with a Garmin Index BPM ran about 16 mmHg low on systolic and about 5 mmHg low on diastolic. Stuff's comparison with a home cuff looked close. Neither is a trial. Whoop has not published a cuff-versus-insight error table that would let you treat MG as a monitor either. Whichever you buy, keep a validated upper-arm cuff in the house if a number will change what you do.
Training, sleep and the rest of the day
Whoop is a coach that happens to sit on a wrist. Strain, Recovery and sleep sit on every membership. Life, the only way to get MG hardware, adds Healthspan and the stress tools that Peak already partially covers, plus ECG and the blood pressure insight. There is still no screen and no GPS. Runs are recorded on the phone. The band stays on for the night, which is why the recovery number exists. Battery in the 14-day range means you are not planning a charge around a 24-hour blood pressure study.
The D3 is a health watch that can also start a workout. TruSleep 5.0, optical heart rate, HRV inside Health Glance, and an ECG in supported countries are real. They are not a Strain target and they are not a coach telling you to swap a threshold session for a walk. Pre- and post-exercise blood pressure only covers running, walking and cycling. The strap comes off for the pool. If your week is intervals, lifting and a team sport, Whoop (or a Garmin) is the device you will still be wearing in March. The tier choice inside Whoop, if you do not need MG, is Whoop 5.0 versus Whoop MG.
Comfort follows the sensor. Whoop's knit band is built to disappear. The D3 is slimmer than the D2, at 11.3 mm with a narrower airbag, and it is still a cuff. Night inflations during an ABPM plan will wake some people. That is a property of ambulatory monitoring, not a software bug.
Cost over three years
The stickers are in different currencies, so do not pretend they are one shop. A UK buyer pays £399.99 once for the D3, plus a strap if the first airbag size is wrong. There is no membership required to see blood pressure. The three-month Huawei Health+ trial is included and then optional.
Whoop Life is $359 in year one and again in year two and year three, about $1,077, and the band goes quiet if you cancel. Peak at $239 a year is the honest Whoop for people who wanted coaching and got distracted by blood pressure. Three years of Peak is about $717 and never produces a cuff reading. If blood pressure insights were the only Life feature you cared about, the D3 is the clearer purchase in any country where Huawei actually sells it.
Data, doctors and phones
D3 reports live in Huawei Health, on iOS 13 and Android 9 or later. You can generate an ABPM summary and take it to an appointment. That is the workflow the watch is designed for. It is a poor workflow if your clinician will only accept an upper-arm ambulatory recorder from a hospital loan scheme.
Whoop reports live in Whoop. You can export trends. You cannot hand over a CE-marked 24-hour blood pressure file, because MG does not create one. Fitcoin sits beside both rather than between them: it reads workouts and steps from Apple Health or Health Connect and does not import either Huawei cuff readings or Whoop's blood pressure insights.
Who should pick which
- Watch D3 if the sentence in your head is "I need systolic and diastolic numbers through a day and a night, on a wrist, in a country where this is certified."
- Whoop Life / MG if the sentence is "I already follow Whoop's Recovery and I want ECG plus a calibrated pressure trend on top." If you do not already follow Recovery, Life is an expensive way to become a person who does.
- Whoop Peak, or no Whoop if blood pressure was marketing. Peak keeps the coach. A Hume Band is the pay-once optical trend if you refuse both the cuff and the subscription.
- An upper-arm cuff, and neither wearable if you are pregnant, your wrist is outside 13 to 21 cm, or you need a number for medication. The wearables are convenience. The cuff is the reference.
Frequently asked questions
Does Whoop MG measure blood pressure like the Huawei Watch D3?
No. The D3 uses an inflatable cuff and reports systolic and diastolic values. Whoop MG estimates insights after calibration with a separate cuff, and Whoop calls that a wellness feature.
Which one is a medical device?
The Watch D3 is CE-MDR certified in the EU for specified blood pressure measurements. Whoop MG is not a blood pressure monitor. Neither should be used to change medication on your own.
Which is cheaper over three years?
The D3 is a one-time £399.99 in the UK. Whoop Life is $359 every year, about $1,077 over three years, and the hardware stops working as a Whoop if you cancel.
Can I use Whoop's coach and the D3's cuff together?
Yes, if you will tolerate two devices. They do not share a blood pressure record. Most people should pick the job they actually have and buy one.
Is the Huawei Band 11 the same kind of product as Whoop?
No. The Band 11 is a cheap screened fitness band without blood pressure. Huawei has only surveyed a screen-free Whoop-style band. It is not on sale.
