Garmin Approach® S44 vs Garmin Instinct® 3 – 50 mm, AMOLEDSize, Specs & Wrist Fit Compared

The Garmin Instinct® 3 – 50 mm, AMOLED wears larger than the Garmin Approach® S44 (50mm vs 43mm 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 14.4mm), so it slides under a cuff more easily.

On the wrist the Garmin Approach® S44 feels lighter (42g vs 59g, case only).
