Epix Pro Gen 2 Sapphire 42mm
Garmin
Instinct® E – 40 mm (010-02932-00)
The Garmin Epix Pro Gen 2 Sapphire 42mm 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 14.1mm), so it slides under a cuff more easily.
On the wrist the Garmin Instinct® E – 40 mm feels lighter (41g vs 63g, case only).
