Garmin Forerunner® 570 - 47mm vs Garmin Forerunner® 945Size, Specs & Wrist Fit Compared

The Garmin Forerunner® 570 - 47mm and Garmin Forerunner® 945 share a near-identical 47mm case, so wrist presence comes down to thickness, lug-to-lug and weight.

The Garmin Forerunner® 570 - 47mm is the slimmer of the two (12.9mm vs 13.7mm), so it slides under a cuff more easily.
