Smartwatch engineered for serious aviation enthusiasts
The Garmin D2™ Mach 1 Pro is the new flagship aviator smartwatch engineered for professional pilots, corporate crews, and serious aviation enthusiasts who demand the very best in flight navigation, situational awareness, health monitoring, and everyday smartwatch capability.
Built around a stunning 1.4-inch always-on AMOLED touchscreen protected by sapphire crystal, the Mach 1 Pro delivers razor-sharp readability in direct sunlight and low-light cockpits alike. Its 51 mm aviation-grade titanium case with diamond-like carbon (DLC) coating and optional vented titanium bracelet weighs just 70 g — making it one of the lightest and toughest premium pilot watches ever created.
Key Features
Compact AMOLED Display with Always-On Visibility
The Forerunner 265S features a bright 1.1-inch AMOLED touchscreen with 416 × 416 resolution and always-on functionality, protected by Gorilla Glass 3. Even in direct sunlight, race pace, heart rate zones, and maps remain crisp and readable without raising your wrist, while the smaller 41 mm case fits comfortably on narrower wrists.
Advanced Training Readiness and Recovery Insights
Garmin’s Training Readiness score combines sleep quality, recovery time, HRV status, acute training load, and stress history to tell you whether today is a hard workout day, an easy recovery run, or a rest day. Morning Report and adaptive daily suggested workouts adjust automatically as your fitness improves or when fatigue sets in.
Multi-Band GPS with SatIQ Precision
SatIQ technology dynamically switches between single-band and multi-band GNSS depending on your environment, delivering ultra-accurate tracking in challenging urban or trail settings while preserving battery life. Whether you’re weaving through city skyscrapers or running under heavy tree cover, distance and pace stay reliable to within a few meters per kilometer.
Built-in Music Storage and Phone-Free Runs
Store up to 500 songs directly on the watch from Spotify, Deezer, or Amazon Music (premium subscription required). Pair any Bluetooth headphones and leave your phone at home—control playback, volume, and skip tracks right from your wrist without interrupting your stride.
Exceptional Battery Life for a Full-Color Smartwatch
Despite the power-hungry AMOLED screen, the 265S lasts up to 15 days in smartwatch mode, 24 hours in GPS-only mode, or 7 days with always-on display and regular workouts. A single charge easily covers an entire training week plus a marathon-length race with music streaming.

Yes. During initial pairing, choose “Migrate from another device” and keep both watches nearby.

No. It is a supplemental pilot aid only (per the manual and FAA/EASA guidance).
