The Huawei Watch D3 produced close daytime readings in one reviewer’s comparisons with an Omron monitor, but the same reviewer recorded an unusual overnight value in each of two 24-hour monitoring sessions. The results, published on November 5, 2026, are individual observations, not clinical validation across users.
Close readings in a small personal test are encouraging observations, not a population-wide accuracy result.
The Watch D3 uses an inflatable wrist cuff
The Watch D3 takes blood-pressure readings with a micro-pump and an inflatable airbag built into its strap. The cuff uses the oscillometric method, which detects pressure changes as the cuff inflates and deflates. That makes its approach different from a blood-pressure estimate based only on optical sensors.
Four daytime comparisons with an Omron M2 Essential
Wareable’s reviewer compared the Huawei Watch D3 with an Omron M2 Essential in four daytime readings. The measurements were taken consecutively, not at the same time.
| Pair | Huawei Watch D3 (mmHg) | Omron M2 Essential (mmHg) |
| 1 | 119/73 | 118/70 |
| 2 | 118/71 | 114/72 |
| 3 | 113/66 | 109/63 |
| 4 | 112/73 | 108/73 |
Wareable reported differences of no more than 5 mmHg for systolic pressure, the first number, and 3 mmHg for diastolic pressure, the second. David Justo of Cadena SER also described the Watch D3’s readings as practically identical to those from a home monitor after several weeks of use.
TechEdit’s separate month-long review compared the watch with an Omron MX3 Plus. It is a different reviewer’s test with a different monitor, rather than another set of the four readings above.
Two unusual readings during overnight monitoring
ABPM means ambulatory blood-pressure monitoring, a series of readings taken over a period of daily activity and sleep. In each of two ABPM sessions, Wareable’s reviewer recorded one unusual overnight reading: 157/93 mmHg in one session and 132/68 mmHg in the other. The 132/68 result differed from readings taken 30 minutes before and after it. Neither overnight reading was compared with the Omron monitor.
YugaTech’s presenter attributed to Huawei a performance claim that at least 88% of measurements fall within 10 mmHg of reference readings, and at least 97% within 15 mmHg. These are manufacturer-attributed thresholds, separate from the reviewers’ individual comparisons.
One user reported a larger gap at high readings
A Reddit user said their own Watch D3 read about 15 mmHg lower for systolic pressure at higher readings. They also reported closer results from a store demonstration unit. The account does not identify why the readings differed or establish a pattern across Watch D3 devices.
Wareable’s month of use was one reviewer’s experience, not clinical validation. The reported comparisons therefore describe individual tests, rather than establishing accuracy across users or blood-pressure ranges.
