Garmin · Portable GPS, Wearables & Apps
The Garmin D2™ Mach 2 – 51 mm in Carbon Gray DLC Titanium with Vented Titanium Bracelet is a GPS smartwatch built for pilots who want aviation tools on the wrist without giving up everyday wearability. A bright 1.4-inch AMOLED touchscreen display is paired with a sapphire crystal lens and titanium bezel, creating a premium, cockpit-ready design.
For time in the air and time on the ground, it combines advanced flight mapping, aviation-focused alerts, and direct-to navigation with health and training features that support performance and recovery. It also adds practical daily usability with a built-in speaker and microphone for phone calling when paired with a compatible smartphone, plus a powerful integrated LED flashlight with red shift mode.
D2™ Mach 2 is built to stay on wrist for extended trips and busy schedules, with battery options for different priorities. It delivers Up to 26 days (13 days always-on) in smartwatch mode, plus modes including Battery Saver Watch Mode: Up to 41 days and GPS Only: Up to 84 hours (65 hours always-on).
Aviation features are designed to support situational awareness with built-in databases and in-flight views. Pilots can use the moving map and HSI (horizontal situation indicator), access METAR and TAF reports, set personal minimums, and use direct-to navigation to the nearest airport or other destinations from the worldwide aeronautical database.
An integrated LED flashlight adds immediate illumination for cockpit checks, preflight tasks, or everyday use. Variable intensities of white light help match the moment, while a dedicated red light setting and red shift mode are available to help preserve night vision when lighting needs to stay discreet.
Durability
The D2™ Mach 2 – 51 mm blends traditional watch styling with purpose-driven construction for flight. It features a 1.4-inch AMOLED touchscreen display protected by a sapphire crystal lens, paired with a titanium bezel and a metal sensor guard. Leakproof inductive buttons support confident operation, and the watch is rated to 10 ATM. The Carbon Gray DLC Titanium with Vented Titanium Bracelet configuration also lists strap material as titanium and silicone; see the specifications below for sizing and weight details.
Navigation
Flight planning and decision-making are supported by aviation mapping that includes airspaces, runways, airports, and flight plan overlay. For a fast view of conditions, the watch can access METARs and TAFs. When paired with a smartphone, the aviation map can display airport METAR flags and allow overlays such as NEXRAD, cloud coverage, winds, and temperature. Configurable alerts can also be set for new reports and changing conditions.
Connectivity
Daily smart features help keep essentials close at hand. When paired with a compatible iPhone® or Android™ smartphone, smart notifications deliver emails, texts, and alerts to the watch. The built-in speaker and microphone support making and taking phone calls through the paired smartphone, and voice command can be used to control watch functions. Music support includes downloading songs and playlists from Spotify, Deezer or Amazon Music accounts for phone-free listening (subscription may be required).
