Amazfit GTR 3 Pro Limited Edition (Black, Stainless Steel)

How accurate is the heart rate monitoring during exercise?

The heart rate sensor uses advanced optical technology but some users report occasional inaccuracies during intense workouts. For best results, ensure the watch sits snugly on your wrist about one finger-width above your wrist bone. Clean the sensor regularly and avoid wearing it too tightly as this can restrict blood flow. The accuracy improves significantly when the watch learns your baseline heart rate patterns over the first few weeks of use.

Can I swim with this watch and what water activities are supported?

Yes, the watch has 5 ATM water resistance, making it suitable for swimming in pools and open water up to 50 metres depth. It automatically recognises pool swimming as one of eight sports with auto-start functionality. The water resistance also covers showering, rain exposure and water sports. However, avoid hot water exposure like saunas or hot showers as temperature extremes can damage the seals.

How does the offline voice assistant work when there's no internet?

The offline voice assistant operates independently of internet connectivity, allowing you to control watch functions through voice commands. You can start sports modes, open health monitoring features, set timers and navigate menus using voice control. This feature is particularly useful during outdoor activities where smartphone connectivity might be limited. The offline assistant complements the online Alexa functionality, ensuring voice control remains available in all situations.

What's the difference between this Limited Edition and the standard GTR 3 Pro?

The Limited Edition features premium stainless steel construction with hand-polished finishing, compared to the standard model's aluminium alloy case. It includes the same core functionality - 150+ sports modes, health monitoring and 12-day battery life. The Limited Edition also comes with enhanced packaging and may include additional premium accessories. The stainless steel construction provides superior durability and a more luxurious appearance suitable for formal occasions.

How many songs can I store and what audio formats are supported?

The watch stores up to 470 songs in its 2.3GB internal memory, with approximately 2GB available for music after system files. Supported formats include MP3 and other common audio formats. Transfer music through the Zepp app on your smartphone via Bluetooth connection. The watch connects to Bluetooth headphones for wireless listening, making it perfect for workouts without carrying your phone. Music playback operates independently once songs are stored locally.

Does the always-on display significantly impact battery life?

The always-on display does consume additional power but the watch still achieves 12 days of typical usage with this feature enabled. The AMOLED technology efficiently manages power consumption by only illuminating necessary pixels. You can disable always-on display to extend battery life further if needed. The intelligent brightness adjustment automatically dims the display in dark environments and brightens it in sunlight, optimising both visibility and power consumption.

How does the automatic sports recognition work?

The watch automatically detects and starts tracking eight specific activities: outdoor running, treadmill, walking, indoor walking, outdoor cycling, pool swimming, rowing machine and elliptical training. Advanced motion sensors and algorithms analyse movement patterns to identify these activities within minutes of starting. You'll receive a notification asking if you want to begin tracking once an activity is detected. This eliminates the need to manually start tracking for common exercises.

Can I customise the rotatable crown functions?

The rotatable crown serves as the primary navigation tool with haptic feedback for precise control. It scrolls through menus, adjusts settings and zooms in on watch faces or apps. While the basic crown functionality is fixed, you can customise what happens when you press the crown button through the Zepp app settings. The crown's smooth rotation and tactile feedback make it easy to navigate even during exercise or when wearing gloves.
