Garmin Instinct® 3 45mm

How long does the battery actually last with solar charging?

The Instinct 3 offers unlimited battery life when worn all day with 3 hours of daily outdoor exposure in 50,000 lux conditions. Without solar charging, you'll get up to 30 days in smartwatch mode. The solar charging works best in bright sunlight - cloudy days and indoor lighting won't provide the same charging power. Real users report getting 10+ days of battery life even with all features enabled, making it excellent for extended outdoor adventures.

Is the built-in flashlight actually useful or just a gimmick?

The LED flashlight is surprisingly practical with variable intensity settings and strobe modes. It provides genuine visibility in dark conditions and can be activated quickly with a double-tap shortcut. Users find it particularly helpful for reading maps at night, finding tent zippers, or emergency signalling. The light is bright enough to be functional whilst being energy-efficient enough not to drain the battery significantly.

How accurate is the GPS and does it work in challenging terrain?

The watch features multi-band GPS with SatIQ technology that automatically selects the best satellite configuration for your environment. This means it can access GPS, GLONASS and Galileo satellites simultaneously for improved accuracy in dense forests, urban canyons and mountainous terrain. The 3-axis compass and barometric altimeter provide additional navigation support when GPS signals are weak.

Can I actually make contactless payments with this watch?

Yes, Garmin Pay works with supported banks to enable contactless payments directly from your wrist. You'll need to set up the feature through the Garmin Connect app and add your supported bank cards. The payment system uses NFC technology and works at most contactless payment terminals. However, availability depends on your bank supporting Garmin Pay - check compatibility before purchasing if this feature is important to you.

How tough is this watch for outdoor activities?

The watch meets MIL-STD-810 standards for thermal and shock resistance and offers 10 ATM water resistance. The 45mm case uses fiber-reinforced polymer with a metal-reinforced bezel for durability. This means it can handle extreme temperatures, impacts and water immersion up to 100 metres. Users report it surviving harsh outdoor conditions including rock climbing, mountain biking and extended backpacking trips without damage.

What health monitoring features does it include?

The watch provides wrist-based heart rate monitoring, advanced sleep tracking and Pulse Ox sensors. It tracks your heart rate 24/7, analyses sleep stages including REM and deep sleep and measures blood oxygen saturation levels. The health monitoring works continuously in the background and syncs data to the Garmin Connect app for detailed analysis and trends over time.

How customisable are the watch faces and data screens?

The 0.9-inch display offers extensive customisation options for both watch faces and activity screens. You can select which data fields appear on your watch face and arrange them according to your preferences. Activity screens can be customised with different metrics for hiking, running, cycling and other sports. The Connect IQ Store provides additional watch faces and apps, though the monochrome display limits visual options compared to colour watches.

Does the incident detection actually work reliably?

The incident detection and assistance features use built-in accelerometers and GPS to detect potential accidents during activities. When an incident is detected, the watch can automatically send your location to emergency contacts via your paired smartphone. The system works best during tracked activities and requires your phone to be nearby for message sending. Users should test the feature and ensure emergency contacts are properly configured in the Garmin Connect app.
