Disappointing Downgrades
on December 31, 2025
Posted by: Greyer Skys Ahead?
I can’t help but feel disappointed in my most recent Garmin purchase; the first time feeling a bit of buyer’s remorse in any Garmin product I’ve owned and that’s a long list.
I just received my D2 Mach 2 watch; my 3rd D2; going back through the Charlie, then Mach 1 and now the Mach 2.
I love the upgraded fitness and tracking tools and experience, no denying that; but the reason I buy the Mach series is for the Aviation Specific tools and features.
In the past the series has always progressed and built upon itself in the aviation sphere and feature set; but not this time!
The new Mach 2 is clearly a step backwards from previous ‘flagship’ models in multiple regards.
To begin, the basic watch face… I have the 51 mm model and the display is huge and a beautiful upgrade from the Mach 1, but the Mach 1 allowed me to add 4 simple data fields around the bezel of the face and keep the 3 aviation weather ‘circles’ (love!); no such luck on the Mach 2. If I want to have some other data, then the aviation circles must come off and I can’t add all 3 circles/aviation weather data to any other watch face…
Seems like an oversight!
Why were all the Aviation features stripped from the Mach 2?
In the world of flight, Mach 2 is twice the speed of Mach 1; yet in this watch, we’re left with only half the Aviation features of the previous version; so that’s slowing down, not speeding up!
It’s never been Garmin’s style to remove what made a product great when upgrading, but that clearly not the case here.
My gut tells me it’s a move to push users to use and subscribe to the Garmin Pilot app; but where is the Airports Glance? Without it, there’s no way to view airport information at all on the watch! All of the database info is in there with regards to runway info and other data because the filters for Direct to and the Airport watch face ‘circles’ have runway specific data presented. Unsure of frequencies or such (because there’s absolutely no way to view airports; only navigate directly to them ((unless you build a flight plan on Garmin Pilot)).
MOS weather is gone, although the new weather features hourly forecasts; which are kind of the same, but unknown as to source, since MOS seems more official.
When using the comparison tool on the shopping website, essentially all of the aviation specific features have been removed.
What gives?!?
I’ll admit, even as a professional corporate pilot, I didn’t use some of the features very frequently at all; but it was nice when I did.
What’s worse though, the features I did use and come to love are gone!
Please reconsider and update the watch to bring back what made it an aviation watch!

Advanced features and ability to customize faces lets you jump between activities with ease. In addition, the aviation functions are a great backup to the plane. Glad I upgraded!

Great watch, the battery last forever over 23 days, but there’s one thing I think garmin should release another aviation watch face with more data to display, apart from that it’s the best watch
