Haylou Watch 3: what it is and why it’s getting attention

Haylou is a Chinese brand from the Xiaomi ecosystem that has gained ground in the Brazilian market by delivering smartwatches with sophisticated design at prices well below well-known competitors. The Watch 3 is the model that the manufacturer positions as the flagship of the main line, with AMOLED display, heart rate sensor and SpO2 (blood oxygen saturation), and design that flirts with the Apple Watch. The question that remains is: can you trust a less-known brand when it comes to health monitoring and everyday user experience?

The short answer is: it depends on what you’re looking for. If you want a beautiful smartwatch with good battery life and well-executed basic features at an affordable price, the Watch 3 is a serious contender. But if you monitor health more critically or want deep integration with Android or iOS, you will find important limitations that need to be considered before hitting the buy button.

Haylou Watch 3 Specs

AMOLED Display: The Strong Selling Point

The AMOLED panel is, without a doubt, the biggest argument in favor of the Watch 3. AMOLED displays produce more vibrant colors and true blacks because each pixel emits its own light, unlike LCD screens that depend on a backlight. In practice, this means the display is much more readable in sunlight and consumes less battery when the background is dark.

Haylou offers hundreds of customizable watch faces in the application, and the 410 x 502 pixel resolution delivers quite reasonable sharpness for the screen size. The maximum brightness is not disclosed in nits by the manufacturer, so if that number is decisive for you, it’s worth checking the updated specs on Haylou’s official website or at the store where you plan to buy.

Health Monitoring: What Works and What Has Limitations

The Watch 3 monitors heart rate continuously and SpO2 on demand. It also records calories, steps, sleep and offers over 100 sports modes. For most users who want to track basic wellness, this covers everyday needs well.

The critical point is GPS. The watch uses assisted GPS, which means it leverages the GPS of the paired phone to trace routes. If you run without your smartphone in your pocket, you won’t have the route map recorded with precision. For light walks and gym workouts this isn’t a problem, but for runners and cyclists who leave without their phone, it’s a relevant limitation.

Haylou Watch 3 health data serves as a trend reference, not medical diagnosis. The manufacturer does not present medical certifications for the sensors, which is standard in this price range. If you have a heart or oxygenation condition that requires precise monitoring, a medical-certified device or a higher-tier wearable would be the right path.

Battery and Real-World Autonomy

Haylou declares up to 12 days of battery life with moderate use. With continuous heart rate monitoring, frequent notifications and always-on display turned off, it’s reasonable to expect between 7 and 10 days in practice, according to public reviews available in forums and specialized channels. This is well above the average of more famous competitors, which typically deliver 2 to 5 days.

Charging is done via a proprietary magnetic base, a common format in smartwatches, but with a disadvantage: if you lose the cable, you need to buy a specific one. There is no compatibility with USB-C chargers or Qi (wireless standard). Keep the cable in a safe place.

Software, App and Phone Integration

The Haylou Watch 3 uses the Haylou Fun application, available for Android and iOS. The interface is simple and does its job of syncing data, installing watch faces and configuring notifications. It has no native integration with Google Fit, Apple Health or Samsung Health directly, which can be a problem for those who already have health history consolidated in another ecosystem.

Notifications arrive on your wrist, but the response is limited: you can view messages and reject calls, but you can’t reply to texts via the watch (except with pre-configured quick replies on Android). Those who use WhatsApp a lot and want convenience will notice this barrier in daily use. Music control works well, as do alarm and stopwatch, features that most people use quite often.

Pros and Cons

Pros:

• Large AMOLED display with good readability
• Battery life of over 7 days in real use, according to public reports
• Modern design with quick-swap strap
• Water resistance of 5 ATM, suitable for casual swimming
• Bluetooth 5.2 with stable phone connection
• Price significantly lower than competitors with AMOLED display

Cons:

• No native GPS on wrist
• Haylou Fun app with no direct integration with Google Fit or Apple Health
• Processor and memory specs not officially disclosed
• Proprietary charging (depends on cable included in box)
• Health monitoring without medical certifications
• Anatel certification needs to be individually verified before purchasing in Brazil

Competitors and Alternatives in Brazil

The entry and mid-range smartwatch market in Brazil has interesting options. See a direct comparison with alternatives found here:

The Xiaomi Redmi Watch 4 is the most direct competitor: it has a similar display, GPS on the wrist and superior declared battery life for a slightly higher price. If the budget allows for the difference, it delivers more for those who practice outdoor sports. For those evaluating other gadgets in the affordable line, such as headphones with good value for money, the complete QCY T13 ANC 2 review follows the same evaluation logic we use here.

Import, Anatel and Warranty in Brazil

This point deserves special attention. The Haylou Watch 3 is not officially sold in large Brazilian retail chains. It appears on marketplaces like Shopee, AliExpress and Mercado Livre, often in direct import from China or through resellers.

Anatel (National Telecommunications Agency) certification is mandatory for devices that use radio frequencies in Brazil, including Bluetooth. Without the Anatel seal, the product may have problems at customs and, technically, should not be sold here. Before buying, consult Anatel’s public database and ask the seller for the certification number. If they don’t know or don’t have it, think twice.

The warranty for imports purchased from stores without legal presence in Brazil is another point of concern. In general, warranty is limited to the seller’s marketplace policy, with no local technical support. If the watch develops a defect outside the seller’s warranty period, repair or replacement may depend on international shipping, which rarely makes sense.

Frequently Asked Questions about Haylou Watch 3

Does Haylou Watch 3 work with iPhone?

Yes, according to the manufacturer, the watch is compatible with iOS 12 or higher via the Haylou Fun application. But integration is more limited on iPhone than on Android: notifications arrive, but customization and access to system features are more restricted due to Apple’s policies.

Is it possible to reply to messages from the watch?

Not freely. The Watch 3 allows you to view notifications and use pre-configured quick replies on Android. There is no keyboard or voice dictation to compose messages directly from the device, according to the product’s official specifications.

Is Watch 3 suitable for swimming?

The 5 ATM certification indicates resistance to immersion in up to 50 meters under static conditions, suitable for pool swimming and rain. The manufacturer, however, does not recommend use in diving with equipment, high-speed water sports or hot water (shower, sauna).

Where to buy Haylou Watch 3 in Brazil more safely?

The safest option is to look for resellers on Mercado Livre or Shopee that have high ratings, sales history and clear return policy. Always ask for the Anatel certification number before confirming your order. Authorized physical stores are rare in Brazil for this brand.

Is It Worth Buying the Haylou Watch 3?

The Watch 3 is an honest smartwatch within the proposition it embraces: beautiful display, long battery life and low price. For those who want their first smartwatch or are upgrading from a basic non-AMOLED model, it delivers a visual and battery experience that surprises positively on paper and, according to public user reports, also in daily use.

The limitations are real and need to be considered: no native GPS, no native integration with major health ecosystems and uncertain warranty in Brazil. If these points weigh on your use, the Xiaomi Redmi Watch 4 or the Amazfit Bip 5 deliver more for a modestly higher cost.

Recommended for: those looking for their first smartwatch with quality AMOLED display, using little outdoor GPS, not depending on Google Fit or Apple Health integration, and wanting to save without sacrificing beautiful design and above-average battery life.

Price range: approximately R$ 250 to R$ 380 in Brazil via marketplaces (prices vary based on exchange rate and seller; check current price before purchasing).
