Garmin Forerunner® 935 vs Garmin Forerunner® 970Size, Specs & Wrist Fit Compared
The Garmin Forerunner® 935 and Garmin Forerunner® 970 share a near-identical 47mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Garmin Forerunner® 970 is the slimmer of the two (12.9mm vs 13.9mm), so it slides under a cuff more easily.
On the wrist the Garmin Forerunner® 935 feels lighter (49g vs 56g, case only).
