Garmin epix™ Pro (Gen 2) – Standard Edition | 42 mm vs Garmin Instinct® E – 40 mmSize, Specs & Wrist Fit Compared

The Garmin epix™ Pro (Gen 2) – Standard Edition | 42 mm wears larger than the Garmin Instinct® E – 40 mm (42mm vs 40mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The Garmin Instinct® E – 40 mm is the slimmer of the two (13.6mm vs 14.2mm), so it slides under a cuff more easily.

On the wrist the Garmin Instinct® E – 40 mm feels lighter (41g vs 63g, case only).
