Amazfit GTR 4 New vs boAt Wave Sigma 3: Amazfit and boAt are some of the well-known brands in smartwatches, each offering new options in 2025: the Amazfit GTR 4 New and the boAt Wave Sigma 3. Both guarantee health tracking, call functions, and fashion designs, but is one truly superior? Let’s dive into a detailed comparison to help you decide which smartwatch fits your lifestyle better.
Processor and Performance: Amazfit GTR 4 New vs boAt Wave Sigma 3
While the Amazfit GTR 4 New runs on ZeppOS 2.0, the boAt Wave Sigma 3 runs on Crest+ OS. Of the two, the interface of Amazfit feels much smoother and more responsive because of its faster performance and better optimization. The boAt Crest+ OS is pretty simple, user-friendly, and more geared toward basic daily usage. Both provide Bluetooth calling, though the connection stability in the Amazfit is a little better, with Wi-Fi and GPS support, features missing in the Wave Sigma 3.
Display and Design
Design is where both watches shine differently. The Amazfit GTR 4 New sports a round stainless-steel dial with a premium finish, with a 1.45-inch AMOLED display offering a 466×466 resolution. The boAt Wave Sigma 3 has a 2.01-inch rectangular display with 240×240 resolution, thus larger but not as crisp. The AMOLED panel on the Amazfit provides richer colors and deeper contrasts, ideal for outdoor visibility. boAt’s display works fine indoors but struggles in sunlight. Amazfit’s 5ATM water resistance edges it past the IP67 protection on boAt’s model.
Battery Life Comparison
Battery backup is a big factor in any smartwatch, and here, the Amazfit GTR 4 New wins comfortably. It houses a 475mAh battery that lasts for up to 12 days, whereas the boAt Wave Sigma 3’s 320mAh cell would run around 7 days. Both of them refill quickly, but if you prefer fewer charging breaks, Amazfit clearly has the advantage.
Fitness Tracking and Health
Both devices are equipped with heart rate monitoring, SpO2 tracking, and step counting. However, Amazfit adds to the precision with features such as sleep tracking, stress monitoring, and a menstrual health tracker. boAt Wave Sigma 3, while offering some basic functions, doesn’t offer advanced sensors such as the altimeter. With more details on fitness and accuracy in data, Amazfit seems much better for serious health tracking.
Connectivity and Calling Features
Both watches support Bluetooth calling and in-built microphones; however, Amazfit has a speaker for voice responses and better sound during calls. GTR 4 New Bluetooth 5.0 and Wi-Fi make it more versatile compared to Wave Sigma 3’s Bluetooth 5.2, still decent but lacking GPS support for outdoor tracking.
Conclusion
If your focus is on fitness tracking accuracy, display quality, and long battery life, then Amazfit GTR 4 New is the obvious winner. But if you just need a trendy smartwatch with basic health tracking and a big display, then boAt Wave Sigma 3 gives better value at a lower price.
