Published on 09/21/2026 at 08:38 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Garmin Descent G1 Solar brings a 45mm case, a sapphire lens, and solar charging to a dive watch built for the wrist underwater and topside. The US launch price was $649.99.
Battery Life And Diving Specs
The owner's manual lists up to 21 days in smartwatch mode, up to 26 hours in GPS mode, and up to 25 hours in dive mode for the Descent G1 Solar. The same table shows 124 days in smartwatch mode with solar and 39 hours in GPS mode with solar.
Garmin says the watch is water rated to 10 ATM, or 100 meters, and the case uses leakproof inductive buttons with a sapphire lens. It also supports multiple dive modes, including air, nitrox, trimix, gauge, apnea, apnea hunt, and closed-circuit rebreather.
What The Watch Adds
The Descent G1 Solar includes a 3-axis digital compass, vibration depth alerts, Garmin Pay, and Connect IQ compatibility. Garmin also lists QuickFit band compatibility and support for Android and Apple smartphones.
The line launched on March 2, 2022, with the Descent G1 at $549.99 and the Descent G1 Solar at $649.99. REI currently lists the Descent G1 Solar at $650.00.
Where It Fits
Garmin International, Inc. is the US sales entity, and Garmin Ltd. is the parent company. For divers who want one watch for dive logs, GPS, and daily wear, the 45mm format keeps the feature set compact.
Against the non-solar Descent G1, the solar model adds charging support and raises the launch price by $100. The solar version is the one with the longer smartwatch battery claim, while dive mode stays at 25 hours.
Descent G1 Solar Watch-Style Dive Computer
Garmin describes the Descent G1 Solar as a rugged watch with dive and smartwatch functions.
Bottom Line For Divers
The Descent G1 Solar sits in the compact dive-computer category, with battery claims and dive modes that match its wrist-worn format. It suits buyers who want Garmin's dive tools plus a smartwatch shell, not a larger premium dive computer.
