Garmin’s latest aviation smartwatch duo puts advanced flight tools on your wrist. The D2 Air X15 and D2 Mach 2 feature avionics data integration, AMOLED touchscreens, and hands-free voice commands. The Mach 2 also adds detailed maps and alerts when weather exceeds your minimums. You can view flight and navigation data from compatible avionics, use PlaneSync and geo-referenced memos, and rely on up to 10 days of battery life. Prices range from $649.99 to $1,499.99.
Overview of Garmin’s New Smartwatches
Both models include AMOLED touchscreens, built-in speakers, microphones, and pilot-focused voice commands. The D2 Air X15 and D2 Mach 2 bring avionics data and crew alerts directly to your wrist. When paired with Garmin Pilot or PlaneSync, they display flight instruments, fuel and electrical status, and send crew messages. The X15 features a 45 mm case with Gorilla Glass 3 and up to 10 days of battery life. The Mach 2 adds detailed aviation maps, terrain shading, and weather alerts tied to your personal minima.
D2 Air X15 Features
The D2 Air X15 uses a 45 mm case with Gorilla Glass 3, an LED flashlight, and PlaneSync compatibility. Its dynamic watch face changes color with flight conditions. You can access fuel, electrical, database, and location data from PlaneSync-equipped aircraft. Voice commands such as “Start Fly activity” improve cockpit workflow. With 10 days of smartwatch battery life, the X15 keeps vital information available during long trips.
D2 Mach 2 Features
The D2 Mach 2 builds on smartwatch essentials with advanced navigation. It includes aviation maps, terrain shading, airspace boundaries, and user-defined waypoints. A live breadcrumb trail records each flight. You get alerts when METARs or TAFs exceed your thresholds—for example, crosswind or visibility limits. Offered in 47 mm and 51 mm sizes with titanium or DLC bezels, the watch is rated for 40 meters of continuous wear.
The Mach 2’s alerting system lets you set custom minima for wind or visibility. For instance, define a 15 kt crosswind threshold or a 3 SM visibility floor. The watch then issues proactive warnings. Its breadcrumb trail records your route for review. Terrain shading and airspace overlays help anticipate constraints during approaches. When paired with Garmin Pilot and compatible avionics, the Mach 2 mirrors navigation data and crew messages to simplify cockpit workflow.
Flight and Navigation Capabilities
The D2 Mach 2 provides aviation mapping with terrain shading, airspace boundaries, VORs, and waypoints. Its live breadcrumb trail tracks your flight in real time. The D2 Air X15 supports PlaneSync status and flight overlays. Both models send alerts when weather exceeds configured minimums, helping pilots identify hazards early.
Integration with Garmin Pilot App
When paired with Garmin Pilot, your watch shows live flight and navigation data from avionics and pushes crew messages to your wrist. You can pull PlaneSync status such as fuel, electrical, and database information directly to the watch. Syncing flight plans and waypoints ensures consistent situational awareness across displays.
Voice Command Functions
Built-in speakers and microphones let you use voice commands like “Start Fly activity” or “Show me the METAR.” You can record geo-referenced voice memos and send texts through Garmin Messenger. Voice control speeds tasks and keeps your focus forward. Commands are processed locally and routed through Garmin Pilot or avionics. You can query METARs, start logs, or tag waypoints by voice. Always confirm critical data on primary avionics before acting.
Design and Build Quality
Garmin blends utility with rugged design. The D2 Air X15 uses a 45 mm case with Gorilla Glass 3 and an LED flashlight. The D2 Mach 2 offers 47 mm and 51 mm versions with titanium or DLC-coated bezels and a 40-meter water rating. The X15’s 10-day battery supports extended travel between charges.
Display and Durability
Both watches feature bright AMOLED touchscreens for excellent sunlight visibility. The X15’s Gorilla Glass 3 resists scratches. The Mach 2’s 40-meter rating supports swimming and diving. Built-in audio hardware enables voice control and alerts without needing a phone, which helps during high-workload phases.
Size and Weight Options
Choose the 45 mm D2 Air X15 for a compact, lighter option with longer battery life. The Mach 2 comes in 47 mm ($1,349.99) and 51 mm ($1,499.99) sizes. The 47 mm offers balanced wearability, while the 51 mm maximizes map visibility. Titanium trims weight, and DLC coatings improve scratch resistance for demanding cockpits.

Pilot-Centric Functions
These smartwatches bring avionics-grade tools to your wrist. You get avionics integration, weather data, voice commands, and crew alerting. The D2 Air X15 and D2 Mach 2 pull navigation and system messages from Garmin Pilot. The Mach 2 also adds detailed maps, breadcrumb tracking, and configurable weather alarms. Pilots can act on real-time flight data without looking down at cockpit screens.
Weather Alerts
The Mach 2 provides configurable weather alerts when conditions exceed your defined limits. Set triggers such as crosswind above 15 kt or visibility below 3 SM. The watch issues push notifications tied to METARs, TAFs, and onboard sensors. These alerts give early notice of hazardous weather both before and during flight.
Remote Status Monitoring
The D2 Air X15 uses PlaneSync to display remote aircraft status. You can check fuel, electrical systems, database versions, and GPS location from your wrist. The feature helps you monitor aircraft systems during taxi, cruise, or shutdown without accessing the main avionics. When paired with a PlaneSync-enabled panel, you can see remaining fuel, alternator voltage, and nav-database dates. This reduces head-down time and improves dispatch efficiency. Ensure aircraft compatibility and connection status before relying on these readings in critical phases.
Pricing and Availability
Retail Prices
The D2 Air X15 costs $649.99. The D2 Mach 2 starts at $1,349.99 for the 47 mm and $1,499.99 for the 51 mm model. The higher price reflects titanium or DLC bezels and extra mapping and weather features.
