The HUAWEI WATCH 6 is available in 42 mm and 46 mm versions, and the main buying decision is whether you prefer the smaller, lighter case or the larger display and longer battery estimates. Huawei’s battery figures are lab-based, while some software and connectivity features depend on your phone, region, and carrier. PhoneArena’s September 2026 review called it a practical, well-rounded smartwatch; that is the publication’s assessment, not an independent test for this review.
Is the HUAWEI WATCH 6 worth buying?
It may suit buyers looking for a feature-rich smartwatch with two case sizes, health and fitness tools, and compatibility with recent Android phones and iPhones. The 46 mm model has the longer manufacturer-estimated runtime and larger display; the 42 mm version is smaller and lighter. Those advantages come with qualifications: Huawei’s estimates depend on usage and watch mode, and features such as eSIM calling, Health Insights, and third-party apps are not universally available.
PhoneArena published a review on September 18, 2026, gave the watch a score of 9, and described it as practical and stylish. Its report said UK availability through Huawei Store and Amazon would begin September 23, 2026, and listed a £399 starting price for the 42 mm model. These are dated UK market details, not confirmation of current stock or pricing.

HUAWEI WATCH 6 42mm vs 46mm
Huawei’s UK specifications distinguish the versions by case size, weight, screen dimensions, and battery estimates. The figures below are manufacturer specifications; strap weight is excluded from the listed weights.
#1 Best Overall

| Specification | 42 mm | 46 mm |
|---|---|---|
| Case dimensions | 42.3 × 42.3 × 10.2 mm | 46.4 × 46.4 × 10.9 mm |
| Weight | Approx. 38 g | Approx. 60 g |
| Display | 1.38-inch LTPO 2.0 AMOLED; 466 × 466; 338 PPI | 1.5-inch LTPO 2.0 AMOLED; 466 × 466; 310 PPI |
| Standard mode, typical battery estimate | 3 days; 2 days with always-on display (AOD) | 4.5 days; 3 days with AOD |
| Battery saver, maximum estimate | Up to 7 days | Up to 11 days |
| Battery saver, typical estimate | 5 days; 3 days with AOD | 7 days; 4.5 days with AOD |
Choose 42 mm if a smaller, lighter watch matters more than screen size or runtime. Choose 46 mm if you want the larger display and the longer estimates in either mode. The pixel dimensions are the same, so the larger model has a lower stated pixel density.
How long does the HUAWEI WATCH 6 battery last?
Huawei’s UK specifications give the estimates in the comparison above; they are laboratory estimates, not independent measurements. In Standard mode, Huawei’s typical-use scenario includes two hours of LTE and 22 hours of Bluetooth phone connection each day, continuous heart-rate monitoring, overnight TruSleep, two ECG measurements per day, notifications, and 200 screen activations per day. It also includes weekly allowances for app use, calls, music, and exercise. Actual runtime varies with use and conditions.
Rank #2
- STYLISH DESIGN, VIBRANT DISPLAY: The lightweight aluminum build blends effortless style with workout durability, while the vivid 1.97" AMOLED display keeps your data easy to read, even under bright sunlight.
- ALL-IN-ONE ACTIVITY TRACKING: The Amazfit Bip 6 fitness tracker watch offers 140+ workout modes including HYROX Race and Strength Training, plus personalized AI coaching and 50m water resistance.
- UP TO 14 DAYS BATTERY LIFE: The Amazfit Bip 6 smart watch powers through your training and recovery for up to two weeks at a time - no nightly charging needed.
- ACCURATE GPS TRACKING & NAVIGATION: Stay on course with free downloadable maps and turn-by-turn directions. Support from 5 satellite systems ensures precise tracking of every move and fast GPS connection.
- 24/7 HEALTH MONITORING: The Amazfit Bip 6 smartwatch provides precise, real-time monitoring of heart rate, sleep, blood-oxygen and stress, empowering you with actionable insights to optimize your health and fitness.
Always-on display shortens the stated Standard-mode estimate for both sizes. Battery saver has separate typical and maximum figures, so its “up to” number should not be compared directly with a typical Standard-mode result. Battery saver also disables several features, including WLAN, Health Glance, X-TAP interaction, Maps, online music, and Watch AppGallery.

Huawei lists Android 9.0 or later and iOS 13.0 or later as the UK system requirements. The listed requirements do not guarantee that every feature works identically on every phone: availability can depend on the companion app version, phone model, region, and software rollout.
Rank #3

- Calling: Huawei lists eSIM calling, but it depends on a supported One Number or Independent Number service, local carrier availability, and any applicable charges.
- Apps and services: Watch AppGallery availability varies by country and region. Health Insights is also available only in certain markets.
- Hardware connections: Huawei lists Bluetooth 5.2, NFC, dual-band GPS/GNSS, and 2.4/5 GHz WLAN.
Both sizes have a rotating crown and side button. Huawei also lists an optical heart-rate sensor, ECG sensor, body-temperature sensor, barometer, compass, ambient-light sensor, depth sensor, accelerometer, gyroscope, and X-TAP sensor.
Health Glance, ECG, and medical limits
Huawei says Health Glance can be started by holding X-TAP for three seconds and produces a report in about 60 seconds, covering up to 11 metrics. The manufacturer explicitly states: “Neither this product nor the Health Glance feature is intended for medical use.” Results are for reference, not a basis for medical research, diagnosis, or treatment. Health-data availability also varies by country and region.
Rank #4
- VIVID 2.07'' AMOLED DISPLAY: Enjoy a large, sharp, and vibrant screen that makes viewing stats and notifications effortless.
- COMPREHENSIVE HEALTH TRACKING: Monitors heart rate, sleep quality, and stress levels around the clock to help you stay on top of your wellness.
- 150+ SPORTS MODES: Supports over 150 activity types with built-in GPS to accurately track your outdoor and indoor workouts.
- LONG-LASTING BATTERY: Up to 24 days of battery life keeps you going without frequent recharging interruptions.
- DURABLE & COMPATIBLE: 5ATM water resistance rating makes it swim-ready, and it pairs seamlessly with both Android and iOS devices.
The presence of an ECG sensor does not establish that the watch can diagnose a heart problem. Huawei’s stated limitation is clear: this product and Health Glance are not intended for medical use. Health Insights is likewise described by Huawei as not intended for medical use.
Is the HUAWEI WATCH 6 waterproof?
Huawei lists 5 ATM and IP69, but these ratings do not mean the watch is suitable for every water exposure. Huawei explains that 5 ATM reflects static-pressure testing and does not mean the watch is waterproof at a depth of 50 metres. The manufacturer separately says free dives are supported to 40 metres under EN13319; scuba, technical diving, and deeper dives are excluded.

- Huawei warns that water resistance is not permanent and may deteriorate with daily wear and tear.
What comes in the box?
Huawei’s UK specifications list a charging cradle including cable. The supplied strap material varies by color and size; the specifications identify EasyCross fluoroelastomer straps for particular variants and list other strap materials for others. These details do not establish that third-party straps will fit, or that you need to buy a replacement charger.
UK availability and price
PhoneArena’s September 18, 2026 report listed a UK starting price of £399 for the 42 mm model and said the watch would be available from Huawei Store and Amazon from September 23. Because those details are dated reporting, check the current seller listing for live stock, price, and the exact size and variant before buying.
