Garmin D2™ Mach 1 vs Garmin Forerunner® 970Size, Specs & Wrist Fit Compared

The Garmin D2™ Mach 1 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 14.5mm), so it slides under a cuff more easily.

On the wrist the Garmin Forerunner® 970 feels lighter (56g vs 70g, case only).
