D2™ Air (010-02173-41)
Garmin
vívoactive® 3 Music (010-01985-01)
The Garmin D2™ Air and Garmin vívoactive® 3 Music share a near-identical 43.2mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Garmin D2™ Air is the slimmer of the two (12.4mm vs 13.6mm), so it slides under a cuff more easily.
On the wrist the Garmin vívoactive® 3 Music feels lighter (39g vs 46.3g, case only).
