Garmin
Forerunner® 45 (010-02156-05)
The Garmin epix™ Pro (Gen 2) – Standard Edition | 42 mm and Garmin Forerunner® 45 share a near-identical 42mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Garmin Forerunner® 45 is the slimmer of the two (11.4mm vs 14.2mm), so it slides under a cuff more easily.
On the wrist the Garmin Forerunner® 45 feels lighter (32g vs 63g, case only).
