Garmin D2 Air X10 Review (2026): Still Worth Buying?

A lightweight aviation smartwatch with genuinely useful pilot tools, but the newer D2 Air X15 makes price the deciding factor in 2026.

D2™ Air X10

Pros

  • Excellent aviation-specific tools
  • Bright AMOLED touchscreen
  • Lightweight and comfortable
  • HSI and Direct-to navigation
  • Worldwide aviation database
  • Automatic flight logging
  • Garmin Pilot integration
  • Good battery life
  • Music, Garmin Pay and calls

Cons

  • No moving aviation map
  • No ForeFlight integration
  • Older health sensor platform
  • No multi-band GPS
  • No ECG
  • No LED flashlight
  • Newer X15 is substantially more capable
  • Always-on display reduces battery considerably
  • Limited appeal for non-pilots

Garmin D2 Air X10 has aged surprisingly well.

Its 1.3-inch AMOLED display still looks sharp, the 51 g body remains comfortable and Garmin's core aviation tools haven't suddenly become useless just because a newer model exists.

Direct-to navigation, HSI guidance, airport information, METAR access and automatic flight logging are all genuinely useful capabilities — particularly as convenient secondary tools or navigation backups.

But pilots should be realistic about what they're buying.

An iPad running ForeFlight or Garmin Pilot provides far more information on a much larger screen, and several pilots say that's where they spend most of their cockpit time anyway. The D2 Air X10 complements those tools rather than replacing them.

And then there's the D2 Air X15.

Garmin's newer model brings a bigger AMOLED display, up to 10 days of battery life, multi-band GPS, ECG, a flashlight, newer training metrics and considerably more sophisticated aviation connectivity. At CA$899.99, it also establishes the price ceiling against which any X10 deal needs to be judged.

That leaves the X10 in an interesting position.

At a substantial discount, it's still a very good aviation smartwatch. Near X15 pricing, there is little reason to choose it.

For a student pilot, private pilot or Garmin Pilot user who finds one at the right price, the D2 Air X10 remains an easy watch to like.

The short version

What to know

What Stands Out

  • Excellent aviation features: Direct-to navigation, HSI, airport data, weather and automatic flight logging put genuinely useful pilot tools on your wrist.
  • Lightweight design: At just 51 g, the D2 Air X10 is comfortable enough for all-day and overnight wear.
  • Excellent AMOLED display: The sharp 416 × 416 AMOLED screen is bright, colourful and supports an always-on mode.
  • Useful navigation backup: Worldwide airport data, Nearest airport and HSI guidance provide a handy backup navigation option.
  • Strong everyday smartwatch features: Music, Garmin Pay, notifications, calls and voice-assistant support make it useful outside the cockpit too.
  • Good battery life: Up to seven days of smartwatch use means far less charging than many full-featured smartwatches.

Where It Falls Short

  • The X15 is much newer: The D2 Air X15 adds longer battery life, multi-band GPS, ECG, a flashlight and newer health and training features.
  • No moving aviation map: Navigation relies on HSI and Direct-to guidance rather than a detailed moving map.
  • No ForeFlight integration: Flight-plan syncing focuses on Garmin Pilot, which limits its appeal for ForeFlight users.
  • Aging fitness features: Everyday fitness tracking is solid, but newer Garmin watches offer much deeper training and recovery insights.
  • Always-on mode hurts battery: Keeping the AMOLED display permanently active can noticeably reduce battery life.
  • Poor value at full price: In 2026, the X10 makes the most sense heavily discounted or used rather than priced close to the newer X15.
