Smartwatch Review within the 9.9 Promotion
The Samsung Galaxy Watch 8 44mm LTE is the latest device from Samsung, distinguished by LTE support, which allows users to make calls, send messages, and use apps without having their phone nearby. This model features a 44mm silver casing (suitable for medium and large wrists), is equipped with full Galaxy AI functionality, enhanced health monitoring (heart rate, sleep, oxygen saturation, ECG), and complete integration with Samsung Galaxy smartphones. With a 63% discount, this is the largest percentage discount on the list, and the price has dropped below 1,280 reais, reaching the lowest price for the Galaxy Watch 8 LTE.
The Garmin Forerunner 55 is the starting point in the world of Garmin sports watches, popular among running beginners. It includes built-in GPS (tracks route, distance, and pace without relying on a phone), wrist heart rate monitor, personal trainer for workouts, smart notifications, and integration with Garmin Connect—the most powerful application for sports analysis on the market. The battery life lasts up to two weeks under normal use. With a 36% discount, it is sold for less than 1,400 reais.
The Huawei Watch GT 7 Pro 46mm represents a premium version of Huawei's latest Watch GT line. Its main advantages are battery life of up to 21 days on a single charge, one of the best in the category in 2026, and the use of premium materials in its 46mm casing. It also offers full health monitoring (heart rate, oxygen saturation, sleep, ECG), built-in GPS, water resistance, and compatibility with Android and iOS. It is available in two colors: classic black (for understated and formal use) and yellow (more vibrant and sporty). With a 44% discount, it costs less than 1,500 reais.
The Garmin Forerunner 165 is a direct successor to the popular Forerunner 55, offering significant improvements. It features an AMOLED screen (unlike the 55's MIP screen—brighter and more colorful), a slightly larger 43mm casing, built-in GPS, wrist heart rate monitor, adaptive personal trainer, and smart notifications, along with Garmin Connect integration. It is ideal for intermediate runners who want a modern visual experience and improved features. With a 33% discount, its price is below 1,850 reais.
The Apple Watch SE 3 is the most affordable latest version of the Apple Watch, released by Apple in 2025 as an entry point into the watchOS ecosystem. The model has a 40mm aluminum casing in 'starlight' color (light and elegant), built-in GPS, health monitoring (heart rate, sleep, physical activity), and seamless integration with iPhone, including all the latest watchOS features. A matching sport band in size P/M is included. With a 27% discount, it costs less than 2,400 reais, making it the most accessible entry into the Apple Watch ecosystem.
The Garmin Vivoactive 6 is the newest model in the Vivoactive series, focused on lifestyle and wellness, with a less technical approach than the Forerunner series (specialized for runners). It combines an elegant look for professional and social use with advanced health features: built-in GPS, wrist heart rate monitor, sensors for various sports (running, cycling, swimming, yoga, strength training), and detailed sleep and stress analysis. It is ideal for those who want a Garmin watch with a more subdued appearance for daily use, in addition to sports. With a 26% discount, it costs less than 2,700 reais.
The Garmin Forerunner 265 Music is a more advanced version of the Forerunner 165, representing premium sports watches for intermediate and advanced runners. It features a high-quality AMOLED screen, a 46mm black casing with a gray accent, multi-band built-in GPS, wrist heart rate monitor, advanced training analysis, and the key 'Music' function: offline music storage and playback directly on the watch (Spotify, Deezer, Amazon Music), allowing running without a phone and connecting Bluetooth headphones directly to the watch. With a 36% discount, it costs slightly over 3,029 reais.
The Apple Watch Series 11 is Apple's new flagship in the standard Watch lineup, released in 2025, with significant improvements in data processing, health sensors, and Apple Intelligence features.

A black sport band in size M/G is included. With a 32% discount, it costs less than 4,000 reais.
How to Choose the Perfect Smartwatch
Choosing the right smartwatch depends on three main factors: your phone's ecosystem, primary use case, and budget. iPhone users are best suited for the Apple Watch Series 11 and SE 3, as they provide the most complete integration and represent a natural investment—the SE 3 serves as an accessible entry point, while the Series 11 offers premium sensors and superior performance. For Samsung Galaxy users, the Galaxy Watch 8 44mm LTE, presented at the lowest price, is an exceptional opportunity due to its integration with Galaxy AI and independent cellular chip, providing premium functionality.
For runners, regardless of the ecosystem, the Garmin Forerunner line is the absolute standard: Forerunner 55 for beginners, Forerunner 165 for intermediate users with an AMOLED screen, and Forerunner 265 Music for advanced users who need offline music. If a Garmin watch with a more casual look for business use is required, the Vivoactive 6 is better suited. And for those who value exceptional battery life (21 days) and wish to enter the Huawei ecosystem, the Watch GT 7 Pro in black or yellow is a premium choice at a competitive price.
The choice comes down to positioning. The Apple Watch SE 3 (within this promotion) is an economical version that combines the core functions of the Apple Watch (GPS, heart rate monitor, iPhone integration, full watchOS) at an affordable price. It is ideal for those new to the Apple Watch ecosystem or who do not require advanced health sensors. The Series 11 is the top model, offering a temperature sensor, ECG, advanced sleep monitoring, always-on display, a more powerful chip, and a full suite of health features. It is designed for those seeking the highest level of health and premium performance. Both models were released in 2025 and are the newest versions.
In the Garmin sports line, there are three different positions. The Forerunner 55 is the starting point, ideal for budget-conscious beginners, featuring a traditional MIP screen (less visual longevity). The Forerunner 165 is the mid-range segment, offering an AMOLED screen (brighter and more colorful) and improved features. It suits intermediate runners who desire a modern visual experience. The Forerunner 265 Music is the upper mid-range segment, combining AMOLED with offline music storage and playback (Spotify, Deezer), multi-band GPS, and advanced analysis. It is ideal for dedicated runners who want to run without a phone and listen to music.
The Garmin line has two different focuses. The Forerunner series is designed for runners—its functions are optimized for running (VO2 max, recovery time, cadence, adaptive training plan), and its design is more sporty, integrating with training apps. The Vivoactive series (Vivoactive 6 in this promotion) is oriented towards lifestyle and general well-being—it combines tracking of multiple sports with a more subdued aesthetic for professional and social use, making it ideal for those who not only run but also want a smartwatch with all health features. The choice is between focusing on running (Forerunner) or lifestyle versatility (Vivoactive).
Yes, especially for those who value exceptional battery life and premium materials. The main advantage of the Watch GT 7 Pro is the battery life of up to 21 days on a single charge, which is one of the best in the category in 2026, significantly surpassing Apple Watch (1-2 days), Galaxy Watch (2-3 days), and Garmin Forerunner (7-14 days). This is perfect for those who dislike charging their smartwatch frequently or take long trips without reliable access to electricity. It is compatible with iOS and Android via the Huawei Health app. The limitation is less integration compared to Apple Watch for iPhone or Galaxy Watch for Samsung—for full functionality, it works better with standard Android.
It depends on usage. The LTE version (within this promotion) has its own cellular chip—this allows making calls, sending messages, and using apps without relying on the phone. A subscription to a cellular line or an additional eSIM is required (most carriers offer a special service for smartwatches with a reduced monthly cost). The Bluetooth version depends on the proximity of the phone for connection but is cheaper and does not require additional monthly fees. Bluetooth is sufficient for home and social use; for runners training without a phone, or those wanting full autonomy, LTE justifies the extra cost.
For iPhone users, the Apple Watch (Series 11 or SE 3) is the natural choice—iOS integration is complete and seamless (notifications, Apple Pay, Siri, music control, health). Other smartwatches (Garmin, Huawei, Samsung) work with iPhone but with limited functionality: they do not allow replying to messages, health integration is partial, and Apple Pay is absent. For dedicated runners with an iPhone, Garmin Forerunner or Vivoactive might be worth the extra cost for superior sports features, even with less integration.
9.9 promotions usually have limited stock and validity—the best prices run out quickly. It is recommended to follow the links, compare models, and take advantage of the discounts while they are available.
