Description
Take your outdoor adventures further with the Garmin Instinct 3 Solar 45mm GPS Smartwatch. Combining rugged construction, advanced fitness tracking and innovative solar charging technology, this versatile smartwatch is designed for athletes, hikers, runners and outdoor enthusiasts.
Featuring a durable 45mm case, metal-reinforced bezel and scratch-resistant Power Glass solar charging lens, the Garmin Instinct 3 is built to perform in demanding environments.
With up to 28 days of battery life in smartwatch mode, potentially unlimited battery life with sufficient solar charging, multi-band GPS and a built-in LED flashlight, this powerful smartwatch provides the tools you need to train confidently and explore further.
Finished in Whitestone with a distinctive Whitestone and Bolt Blue silicone strap, it combines rugged outdoor functionality with contemporary styling.
Power Glass Solar Charging Technology
Spend more time exploring and less time charging with Garmin's Power Glass solar charging technology.
The Instinct 3 Solar uses sunlight to supplement its rechargeable battery, helping extend battery life during outdoor activities.
In standard smartwatch mode, the watch provides up to 28 days of battery life without solar assistance.
With sufficient daily sunlight exposure, Garmin specifies potentially unlimited battery life in smartwatch mode.
This makes the Instinct 3 Solar particularly appealing for hiking, camping, endurance training and extended outdoor adventures.
Solar charging performance depends on sunlight intensity, exposure duration and operating conditions. Garmin's unlimited smartwatch battery-life estimate assumes all-day wear with three hours outdoors daily in 50,000 lux sunlight.
Rugged 45mm Construction
Built for demanding environments, the Garmin Instinct 3 Solar features a durable fibre-reinforced polymer case and metal-reinforced bezel.
Its rugged construction is designed to meet relevant military standards for thermal, shock and water resistance.
The scratch-resistant Power Glass lens helps protect the display while supporting solar charging.
With a compact 45mm case and a weight of just 52g, the watch offers an excellent combination of durability and everyday comfort.
The Whitestone finish and Whitestone/Bolt Blue silicone strap create a distinctive appearance suitable for outdoor activities and daily wear.
Sunlight-Visible Monochrome Display
The Garmin Instinct 3 Solar features a high-contrast monochrome display designed for excellent readability outdoors.
Its 0.9-inch memory-in-pixel display provides clear access to activity statistics, navigation information and health metrics.
The display features a resolution of 176 × 176 pixels and uses an energy-efficient design to help maximise battery life.
Unlike the Instinct 3 AMOLED models, the Solar version prioritises battery efficiency and outdoor visibility rather than a full-colour display.

Additional navigation functions include breadcrumb-style route navigation, waypoint tracking and TracBack routing.
