Garmin Forerunner® 570 - 47mm vs Garmin Instinct® 3 – 45 mm, Solar, Tactical EditionSize, Specs & Wrist Fit Compared

The Garmin Forerunner® 570 - 47mm wears larger than the Garmin Instinct® 3 – 45 mm, Solar, Tactical Edition (47mm vs 45mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The Garmin Forerunner® 570 - 47mm is the slimmer of the two (12.9mm vs 14.9mm), so it slides under a cuff more easily.

On the wrist the Garmin Forerunner® 570 - 47mm feels lighter (50g vs 52g, case only).
