D2™ Air — Frequently Asked Questions
Will the Garmin D2™ Air fit my wrist?
The Garmin D2™ Air looks balanced on flat wrist widths of roughly 45–62mm (about 12.0–16.6cm circumference). Drag the slider above to check it against your own measurement.
How long does the Garmin D2™ Air battery last?
Between 6 hours and 5 days per charge, depending on the power mode. Garmin rates Smartwatch at 5 days and GPS with music at 6 hours; the chart above lists all 4 modes.
How does the Garmin D2™ Air battery compare with other Garmin watches?
At 5 days in everyday use it ranks #234 of the 257 Garmin watches in our database — below the middle of the range. The full ranking, including GPS and power-saving figures, is on our Garmin battery life comparison.
Is the Garmin D2™ Air thick for a 43mm watch?
At 12.4mm, thinner than 81% of 43mm watches, so it slides under a cuff more easily than most of its size. Thickness, not case width, is what decides whether a watch catches on a shirt cuff.
What other watches are the same size as the Garmin D2™ Air?
OnePlus Watch 3 43mm, Oppo Watch X2 Mini, Omega Speedmaster Moonphase Stainless Steel / Black Meteorite / Bracelet, Zenith Defy Extreme Diver Shadow / Bracelet all sit within half a millimetre of the Garmin D2™ Air's 43.2mm case, so they cover the same amount of wrist.
