Question 1

Where can I buy the Huawei Watch D3?

Accepted Answer

The Huawei Store and Amazon UK sell it at £399.99, and it is also sold in selected European markets. It is not sold in the US, where the Wellue BPW1 is the nearest inflatable-cuff alternative. The buy box above shows the current price.

Question 2

Is the Huawei Watch D3 on sale?

Accepted Answer

The Huawei Store and Amazon UK were selling at the full £399.99 launch price after the 23 September 2026 release. The discounted option is the older Watch D2 at around £350, which takes the same measurement. Check the buy box above for the current D3 price.

Question 3

Is the Huawei Watch D3 accurate?

Accepted Answer

Worn on the same wrist and checked against the same Omron arm cuff, it was 95 per cent accurate, while the Wellue BPW1, the other inflatable-cuff watch, was 87 per cent. Across four people, it was 92 per cent accurate on the top number and 90 per cent on the bottom, and it usually read low. The D2 uses the same measurement method and met the AAMI/ESH/ISO Universal Standard in a 2025 independent study, but the D3 has not yet had its own.

Question 4

How many points out is the Huawei Watch D3?

Accepted Answer

Across four people, it read about 10 points low on the top number and 8 points low on the bottom, against an Omron arm cuff. The range was 5 to 14 points on the top number, so check it against your own cuff.

Question 5

Is the Huawei Watch D3 more accurate than the D2?

Accepted Answer

Not according to Huawei. It measures blood pressure the same way, and Huawei claims no improvement in accuracy. I have not tested the D2. The D3 is 2mm thinner, has a brighter 1.92-inch screen, and adds a pre- and post-exercise blood pressure mode and arrhythmia analysis. The D2 costs £50 less while stock lasts.

Question 6

Can you sleep in the Huawei Watch D3?

Accepted Answer

Yes. It takes readings automatically overnight for its 24-hour report. I wore it overnight several times, and neither the strap nor the inflation affected my sleep.

Question 7

Does the Huawei Watch D3 work with an iPhone?

Accepted Answer

Yes. It works with iOS 13.0 or later through the Huawei Health app. On Android, Huawei lists Android 8.0 or later, but several features require Android 9.0.

Question 8

Can I buy the Huawei Watch D3 in the US?

Accepted Answer

No. It is sold in the UK and selected European markets. The Wellue BPW1 is the nearest inflatable-cuff alternative on sale in the US.

Question 9

How long does the Huawei Watch D3 battery last with automatic readings?

Accepted Answer

In my testing, 36 to 40 manual readings used 14 per cent of the battery, which works out at roughly 250 to 285 readings a charge. Huawei claims up to 6 days of typical use, including six blood pressure readings a day, and one day with 24-hour ambulatory monitoring enabled.

Question 10

Can the Huawei Watch D3 replace a home blood pressure cuff?

Accepted Answer

No. The top number read low against an Omron arm cuff on every person I tested, by up to 27 points on one reading. Use it to track trends and check anything that matters on a validated cuff. Huawei&#8217;s own guidance says never to diagnose, treat yourself or adjust medication based on its readings.

Question 11

Is the Huawei Watch D3 waterproof?

Accepted Answer

Not for swimming or showering. Huawei&#8217;s Chinese specification lists IP68, but both the UK and Chinese pages say to remove it before swimming, showering, saunas or hot springs, and liquid damage is not covered by the warranty. Wipe it dry before taking a blood pressure reading if it gets wet.
