The Garmin Instinct 3 is more than just an upgrade—it’s a full-fledged transformation of one of Garmin’s most beloved rugged smartwatch lines. Now in its third generation, the Instinct 3 introduces a stunning AMOLED display, improved solar charging, and tactical-ready features, all while maintaining the bulletproof durability the series is known for. Whether you’re a backcountry explorer, tactical professional, or data-driven athlete, this may be the most well-rounded Instinct yet.
What’s New in the Garmin Instinct 3?
1. AMOLED Display (Optional)
For the first time, Garmin offers an AMOLED screen in the Instinct lineup. Crisp, vibrant, and visible even in direct sunlight, the AMOLED option elevates the user experience significantly, especially when navigating maps, glancing at metrics, or using smart features.
AMOLED brightness does come at the cost of battery life, though Solar charging helps offset this (more on that below).
2. Improved Solar Charging
Garmin’s Power Glass™ solar lens technology gets a boost in the Instinct 3. In sunny conditions, the watch can achieve:
- Up to 70 days of battery life in smartwatch mode with solar
- Unlimited battery in battery saver mode with solar
This makes the Solar version especially appealing to adventurers and military users operating in remote areas.
3. Advanced Training and Health Metrics
Borrowing features from the Forerunner and Fenix series, the Instinct 3 now includes:
- Training Readiness
- Heart Rate Variability (HRV) Status
- Sleep Score and Sleep Coaching
- Pulse Ox, Barometer, Compass, and Multiband GPS
