Forerunner® 745 (010-02445-00)
Garmin
Vivomove 3
The Garmin Forerunner® 745 and Garmin Vivomove 3 share a near-identical 43.8mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Garmin Vivomove 3 is the slimmer of the two (11.3mm vs 13.3mm), so it slides under a cuff more easily.
