Garmin · Diving
The Garmin Descent™ G2 in Black with Black Band is a watch-style dive computer and GPS smartwatch built for divers who also want robust training and everyday wear features. A bright 1.2-inch AMOLED display helps keep key data easy to read, while the sapphire crystal lens and leakproof inductive buttons are designed for time in and around the water.
Beyond the dive site, Descent™ G2 supports advanced training features and 100+ sports apps, plus 24/7 wellness tracking. Dive logs can be stored on the watch and reviewed in the Garmin Dive™ smartphone app, making it simple to look back on past dives between trips. Battery life is rated up to 10 days in smartwatch mode.
Descent™ G2 combines a 1.2-inch AMOLED display with a sapphire crystal lens and leakproof inductive buttons for confident use during dives. It carries a Dive (100 meters) water rating, and its bright color display is designed to keep critical information easy to see while underwater.
With support for multiple dive modes, Descent™ G2 tracks diving from recreational to technical, freediving and pool apnea. It can automatically save dive entry and exit locations, store dive logs on the device, and sync your log to the Garmin Dive™ Mobile app for review and organization.
On land, Descent™ G2 adds training features and a wide range of activity profiles, along with Garmin Connect™ for reviewing health and fitness information in a free, zero-subscription app. Smart notifications work when paired with a compatible iPhone® or Android™ smartphone.
Durability
Descent™ G2 is designed to cover a broad range of underwater use cases with single-gas, multi-gas, gauge, APNEA mode, APNEA hunt mode and Pool APNEA. It uses Bühlmann ZHL-16c with gradient factors and supports gas mixes of Air, Nitrox and Trimix up to 100% O2; 1 bottom gas and up to 11 deco and/or backup gasses. A built-in dive planner provides basic NDL plus a multi-gas deco planner, while audible and vibration alarms can be customized per dive mode based on depth or time.
Navigation
For orientation below the surface, Descent™ G2 includes a built-in 3-axis dive compass with adjustable heading and quick changes to 90R, 90L and reciprocal, plus direction back to the set heading. NDL Aware™ depth metrics work in real time to show how depth changes can impact no-decompression limit (NDL). A surface diver status widget summarizes key information such as surface interval and loading metrics, and the watch also supports tides to help track ocean conditions.
Design
This configuration uses a silicone strap and features a bezel and case made from fiber-reinforced ocean-bound plastic, with 100% of the plastic used in the housing, bezel and buttons made with recycled ocean-bound plastics. It is QuickFit® watch band compatible (22 mm) and sized at 45.5 x 45.5 x 15.2 mm. Weight is 65 g (case only: 41 g), and internal memory/history is 4 GB for storing activity and dive information.
