Our take on the Instinct 3 GPS Smartwatch Solar

The Garmin Instinct 3 Solar is a rugged GPS smartwatch in the Instinct line, built for outdoor use with a fiber-reinforced polymer case and a scratch-resistant display. Its headline feature is solar charging that Garmin rates for unlimited battery life in smartwatch mode with enough sun, plus multi-band GPS with SatIQ for accurate tracking in tough terrain. It adds a built-in flashlight, 24/7 heart rate, HRV status, stress tracking and a Morning Report. It suits hikers, runners and outdoor workers who want durability and long battery over a color touchscreen and smart features. Against the Apple Watch and Galaxy Watch it trades app ecosystem and a bright touch display for battery life and toughness; against the Instinct 2 it adds the flashlight and multi-band GPS.

Questions and answers

Is the Instinct 3 Solar worth it over the Instinct 2?
It adds a built-in flashlight and multi-band GPS with SatIQ, which improves tracking accuracy. If you already own an Instinct 2 and don't need those, the upgrade is modest.
Does solar charging really give unlimited battery life?
Garmin rates unlimited battery life in smartwatch mode only with sufficient sun exposure, such as several hours outdoors daily. In GPS mode solar adds charge but does not make the battery unlimited.
How does it compare with the Apple Watch?
The Instinct 3 Solar lasts far longer per charge and is tougher, but it has a dimmer display and far fewer apps. The Apple Watch is better for smart features and a bright screen.
Does it have music storage or contactless payments?
This model has no onboard music storage and no Garmin Pay. It focuses on GPS, health tracking and battery life.
What is in the box?
The watch and a charging cable. It does not include a spare band or wall adapter.
Is it good for swimming?
It is water-rated for swimming and has pool and open-water modes, but the buttons and display are best used on land.
