Solar Power. Rugged Soul. Built for Every Adventure.

The Garmin Instinct 3 45mm Solar Twilight combines the legendary toughness of the Instinct series with solar charging, a built-in flashlight and the most comprehensive training and navigation features ever offered in a rugged GPS watch.

Solar Charging for Extended Battery Life

The solar-charged display delivers up to 40 days in smartwatch mode with solar charging and up to 260 hours of GPS with solar. The more you are outside, the less you charge.

Built-In LED Flashlight

A built-in LED flashlight with variable intensity settings and a safety strobe mode makes the Instinct 3 Solar the ideal training and adventure companion when daylight runs out.

Multi-Band GPS with SatIQ Technology

Multi-band GNSS with SatIQ provides superior positioning accuracy while intelligently switching modes to optimize battery life, giving you the accuracy you need when it matters and the endurance you need when it counts.

Advanced Training and Sleep Features

Training load focus, training load ratio, multisport auto-transition, Garmin Pay, sleep coaching and nap detection are all new additions that make the Instinct 3 Solar a far more capable training platform than any previous Instinct model.

Military-Grade Rugged Construction

Tested to U.S. military standards for thermal, shock and water resistance, with a metal-reinforced bezel for additional display protection.

Battery Life and Water Resistance

Up to 40 days in smartwatch mode with solar. Up to 60 hours in GPS mode without solar. Rated to 10 ATM water resistance.
