Balanced Fit7.5mm clearance. Comfortable everyday wear with room to spare.

The Garmin fēnix® 7 Pro – Solar Edition wears larger than the Garmin Instinct® E – 40 mm (47mm 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 14.5mm), so it slides under a cuff more easily.

On the wrist the Garmin Instinct® E – 40 mm feels lighter (41g vs 79g, case only).
