Approach® S44 (010-03009-00)
Garmin
Instinct® E – 40 mm (010-02932-00)
The Garmin Approach® S44 wears larger than the Garmin Instinct® E – 40 mm (43mm vs 40mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Garmin Approach® S44 is the slimmer of the two (11.4mm vs 13.6mm), so it slides under a cuff more easily.
