The best smartwatches under 500 reais to buy in 2026

Finding a decent smartwatch for up to 500 reais in Brazil isn’t impossible, but it requires attention. The price range is competitive, full of options that promise a lot in the ad photo and deliver little on the wrist. The good news is that in 2026, some established brands have reached this level with features that were previously exclusive to more expensive watches, such as blood oxygen monitoring (SpO2), integrated GPS, and AMOLED screens with good visibility in the sun.

This guide is for you who wants to stop using your phone to check notifications during a meeting, wants to control a basic running or gym workout, and needs something that lasts at least a full day on battery. It’s not for those who want to replace the Apple Watch or Galaxy Watch Ultra, and not for those looking for advanced features like clinical ECG or GPS route mapping. For that profile, the budget needs to be much larger.

The short answer: in this range, the best value for money available in Brazil are the Amazfit Bip 5, the Xiaomi Smart Band 9 Pro, and the Realme Watch 3. Each one serves a different profile, and the right choice depends on what you prioritize.

Comparison table: smartwatches under 500 reais in 2026

Prices checked in Brazilian stores in 2026; vary according to seller and promotions.

Screen and design: what makes a difference day to day

The screen is the first point of contact with the watch, and here there’s an important division between technologies. AMOLED (Active Matrix Organic Light Emitting Diode) offers deeper blacks, high contrast, and vibrant colors, plus it consumes less battery when the background is dark. LCD is cheaper to produce, but tends to lose visibility in bright sun if maximum brightness is low.

In the Xiaomi Redmi Watch 5, the 2.07-inch AMOLED screen is the largest on the list and impresses for the price. According to the manufacturer, maximum brightness reaches 2,000 nits, which means comfortable reading even in intense sunlight. The Xiaomi Smart Band 9 Pro brings a 1.74-inch AMOLED screen in a slimmer format, similar to a boosted smart band, which appeals to those who prefer something discreet.

The Amazfit Bip 5 uses LCD, but makes up for it with a larger screen (1.91 inches) and good readability under normal conditions. The Realme Watch 3 also uses LCD and has more modest brightness, being more suitable for indoor environments or casual use. If visibility in the sun is a priority for you, go with AMOLED without hesitation.

Battery and autonomy: where this price range shines

Long battery life is, in practice, the main advantage of more affordable smartwatches over premium ones. The Galaxy Watch 7 or Apple Watch Series 10 require daily charging. Here, the story is different.

The Xiaomi Redmi Watch 5 leads with up to 24 days according to the manufacturer, but that number considers light use and always-on screen disabled. With active GPS and continuous heart rate monitoring, autonomy drops significantly. Realistic use for most people falls between 7 and 12 days, which is still far superior to what premium watches offer.

The Huawei Band 9 delivers up to 14 days and is the most efficient on the list relative to size, but gives up integrated GPS. This means it uses your phone’s GPS to map running routes, which requires the smartphone to always be nearby during training. For light walks or gym sessions, it makes no difference. For trails and runs outdoors without a phone, it’s a real limitation.

GPS and health monitoring: what to expect in this range

Integrated GPS means the watch has its own satellite positioning chip and can map your route without depending on your phone. All models in the table, except the Huawei Band 9, have this feature. Accuracy varies, and here it’s important to have calibrated expectations: for street runs and simple trails, it works well. For technical navigation or mountaineering activities, you’ll need a more robust and expensive watch.

SpO2 (blood oxygen saturation) monitors the percentage of oxygen in red blood cells using an optical sensor on the back of the watch. It’s useful for getting a general sense during exercise or identifying variations during sleep. All listed models offer this feature, but none are certified medical devices for clinical diagnosis.

Continuous heart rate monitoring, sleep tracking, and menstrual cycle detection (available in some models) are features that appear in even the most basic smart bands today. The real differentiator in this range is the quality of the software and associated app. The Zepp (Amazfit) and Mi Fitness (Xiaomi) are well-rated and available in Portuguese. Huawei’s app works well, but on some devices requires installing Huawei AppGallery, which can be an extra friction depending on your Android.

Compatibility, homologation, and buying in Brazil

This is a point Brazilian readers need to consider carefully. Anatel homologation is the process by which the regulatory agency certifies that a device is suitable for use in the national territory, respecting radio frequency emission standards. Smartwatches with Bluetooth need this homologation to be legally sold in Brazil.

Xiaomi and Amazfit models sold by official distributors and major marketplaces like Mercado Livre, Amazon Brasil, and Magazine Luiza are generally versions with Anatel homologation. Always check the Anatel homologation number in the product description before buying. Models imported directly from sites like AliExpress may be uncertified versions, which brings customs risk and complicates technical support.

The legal warranty in Brazil is 90 days for used products and 1 year for new products, regardless of what the manufacturer offers. Buying from sellers operating officially in Brazil guarantees this support. Xiaomi has technical assistance in several capitals. Amazfit (Zepp Health brand) operates through distributors, so it’s worth confirming regional support before buying.

Frequently asked questions about smartwatches under 500 reais

Do cheap smartwatches really measure blood pressure?

Most smartwatches in this price range display a blood pressure estimate, not a clinical measurement. This data is generated by algorithms based on heart rate and other optical sensors, and does not replace a calibrated sphygmomanometer. Use it as a trend reference, not as a diagnosis.

Is it worth importing a smartwatch from AliExpress to save money?

It depends on the risk you accept. Models imported without Anatel homologation can be held at customs, and technical support is usually non-existent in Brazil. If the product arrives defective, you’ll probably bear the cost of international shipping for replacement. For most buyers, the model sold in Brazil with warranty is the safer route.

Does a cheap smartwatch work well with iPhone?

It works for the basics: notifications, music control, health monitoring. But iOS has restrictions for third-party apps, so some watch features may be limited or absent compared to Android use. Check specific compatibility with your current iOS version before buying.

How long does a smartwatch in this price range last?

Physical durability depends on how you care for it, but the biggest risk is software support. Manufacturers like Xiaomi and Huawei usually maintain updates for 2 to 3 years for the most popular models. After that period, the watch may continue to work, but without new features or security fixes. It’s a real difference compared to premium watches with longer support cycles.

What to consider before completing the purchase

The best choice under 500 reais is not the one with the most features on the spec sheet, but the one that fits your actual use. If you run three times a week and want to leave your phone on the treadmill, integrated GPS and at least a week of battery are non-negotiable. If you just want to stop pulling your phone out of your pocket every notification at work, any model on the list solves this well.

Before buying, check if the model has Anatel homologation, if the seller offers a receipt, and if there’s technical support in your city or region. For those assembling a complete productivity and mobility setup, smartphone choice also impacts watch experience, and you can read more about it in good phone up to 2 thousand reais: how to choose in 2026. A good smartwatch doesn’t need to be expensive, but a bad purchase can cost more than the initial savings.
