Not completely user friendly
on June 11, 2026
Posted by: Jaysonic
It’s a great watch, but I don’t love that you have to go into 4 or 5 different menus on the watch EVERY time you change locations, before the nearest airport, weather, etc will update. Then any time you change time zones, you have to get into the Garmin Connect APP to update the time zone on the watch. Even when it’s connected to your phone. That does update every time you change zones.

Flight upgrade
on May 13, 2026
Posted by: alfred Vak
It’s been almost three months since I bought this amazing watch, and I have no regrets. It’s the perfect supplement for pre-flight, flight, and post-flight activities. The synchronization with the G1000 is amazing.

Nice update, improvements over Mach 1
on May 7, 2026
Posted by: MinnesotaWT
My perspective is based on I sold my Mach 1 and bought the Mach 2 as I am a nerd that way.
Unless you buy the pro with the LTE and satellite communications, this is a point upgrade not a dramatic change over the Mach 1. I did not buy the Pro because my iPhone has the same satellite emergency message send, and my wife has an Apple watch with LTE and has never used it for a call or a message...plus why only a gross leather band Garmin? The premium watch doesn't get the premium band?
I do love how multi functional this is from flying to golfing to running, fishing, and on and on. I use so many of the tools and functions on this watch it is worth every penny as I don't need a separate golf GPS, I don't need a separate running tracker, I love the consolidated aviation weather and the amazing screen and colors, and the best part is the crazy 25+ days without needing to recharge. Garmin addresses the biggest pain point all other watch manufacturers on the planet can't solve for which is battery life.
Another solid device I recommend to anyone.

Super Features; AutoFly / GPS struggle in cockpit
on May 4, 2026
Posted by: ARMYAV8R
Upgraded from the D2 Bravo Titanium. Fitness Features and functionality are the best in the industry. Great touchscreen and button functionality. AMOLED is very clear and exceptional battery life. Aviation features are great but disappointing as they require strong GPS connectivity which struggles in the cockpit. AutoFly capability, which I loved in the D2 Bravo, doesn’t work half as well if at all for me so rather disappointed with that as a pilot who flies a lot. Love the all black case and titanium band. Very cool looking and comfortable. Maps are detailed but slow to load and update.

Too complicated.
on January 16, 2026
Posted by: Dona
There are no online videos showing how to use all the watch functions. I found it had too many features, and couldn't determine how to use all of them. Too complicated, I returned the watch I received for Christmas.

Fitness, Aviation, Day at a Glance, Battery Life!
on January 12, 2026
Posted by: JetJock
I'm a long time Apple Watch user. That is great, but I love this watch better. First, battery life is weeks, not 18 hours. Second, it's handsome and an eye-catcher, not an everyman's watch. I didn't realize how much fitness and health is built in. Top notch! And of course, if your a pilot, like me, you'll love that it is a true pilot's watch. That's not an afterthought, is is core to the watches base functions. The light is highly useful. And, to my surprise, it's light. Oh, and having both buttons and a swipable screen is great.

Garmin's D2 Mach 2 Home Run!
on January 4, 2026
Posted by: Garmints
I received the Garmin D2 Mach 2 Aviation Smartwatch as a Christmas present from my wife, and without hesitation, it is the greatest aviator smartwatch I have ever owned. From the moment I put it on, the build quality and attention to detail were obvious. The watch is rugged yet refined, with a display that’s incredibly crisp and readable in all lighting conditions—whether I’m in the cockpit, outdoors, or just going about my day. Garmin clearly designed this with real pilots in mind. The aviation-specific features are outstanding. Direct-to navigation, airport and weather information, Pulse Ox, and advanced flight tools are seamlessly integrated and intuitive to use. It’s not just a smartwatch that includes aviation features—it’s a true aviation instrument that also happens to be an exceptional everyday smartwatch. Battery life is excellent, performance is smooth, and the health and fitness tracking are a welcome bonus. It transitions effortlessly from flight operations to daily wear without feeling bulky or out of place. Simply put, the D2 Mach 2 sets the standard for aviation smartwatches. If you’re a pilot looking for a reliable, feature-rich, and beautifully built watch, this is it. Garmin absolutely nailed it—and my wife absolutely crushed this gift. Highly recommended.

Missing many features from the D1 Model
on January 2, 2026
Posted by: AZPilot
I purchased the watch, was super excited. But was disappointed when started to use the watch. For some reason, this model D2 is missing many features that my D1 has. I will be returning the D2.
The graphic of Attitude/Altimeter is missing
Runway info gone
Over complicated the menus
