Instinct 3 Solar Tactical Edition 45mm
Garmin
Instinct® Crossover Solar (010-02730-11)
The Garmin Instinct 3 Solar Tactical Edition 45mm and Garmin Instinct® Crossover Solar share a near-identical 45mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Garmin Instinct 3 Solar Tactical Edition 45mm is the slimmer of the two (14.9mm vs 16.2mm), so it slides under a cuff more easily.
On the wrist the Garmin Instinct 3 Solar Tactical Edition 45mm feels lighter (52g vs 65g, case only).
