Garmin Instinct® E – 40 mm (010-02932-00)
Case: 40mmL2L: 40mmThick: 13.6mm
Balanced Fit7.5mm clearance. Comfortable everyday wear with room to spare.

The Garmin Approach® S50 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® S50 is the slimmer of the two (11.4mm vs 13.6mm), so it slides under a cuff more easily.

On the wrist the Garmin Approach® S50 feels lighter (29g vs 41g, case only).
