Garmin · Portable GPS, Wearables & Apps
The Garmin D2™ Air X15 in Slate with Black Silicone Band is a GPS smartwatch designed for pilots who also want a modern, everyday wearable. It combines flight-focused tools such as Direct-to navigation, HSI course guidance and aviation weather access with a bright 1.4-inch AMOLED touchscreen display.
Beyond the cockpit, it supports training and wellness with 24/7 monitoring features, suggested workouts and a broad selection of sport profiles. A built-in speaker and microphone add on-wrist calling and voice features when paired with a compatible smartphone, while the integrated LED flashlight with red shift mode offers practical illumination for day-to-night use.
D2™ Air X15 supports phone-free Direct-to navigation to the nearest airport or to a selected location or waypoint using the worldwide aeronautical database. HSI course guidance helps visualize whether the watch is left or right of the intended track, making it a useful companion for situational awareness in flight.
With a built-in speaker and microphone, the watch can make and take phone calls when paired with a compatible smartphone. It also supports voice commands for controlling watch functions, and it can use a phone’s voice assistant to help respond to text messages and handle other everyday interactions.
An integrated LED flashlight provides variable-intensity white illumination plus a red light option for low-light use. Red shift mode is also available to help preserve night vision. It’s a practical feature for the cockpit, preflight checks and after-hours tasks when quick light access matters.
Display
This configuration pairs a Slate case with a Black Silicone Band and a 45 mm stainless steel bezel. The 1.4-inch AMOLED touchscreen is protected by a Corning® Gorilla® Glass 3 lens and delivers 454 x 454 pixels for crisp readability. The case is made with stainless steel and fiber-reinforced polymer, includes Quick Release bands support (22 mm, Industry standard), and carries a 5 ATM water rating for daily use.
Durability
For preflight planning and in-flight awareness, D2™ Air X15 can display aviation weather information, including METARs and TAFs, with details such as winds, temperatures and forecast data. Configurable alerts can be set for new reports and changing conditions. It also includes aviation-focused utilities such as multiple time zone displays with a UTC pointer plus a sunrise/sunset widget that includes civil twilight.
Health
D2™ Air X15 supports 24/7 health and wellness monitoring features including wrist-based heart rate, advanced sleep monitoring, respiration tracking, Pulse Ox, Body Battery™ energy monitoring and lifestyle logging in the Garmin Connect™ app. Training tools include daily suggested workouts that adapt after every run or ride, training readiness, and training status, helping guide day-to-day decisions based on sleep, recovery and performance trends.
