Balanced Fit5mm clearance. Comfortable everyday wear with room to spare.

The Garmin Instinct® 2X Solar - Tactical Edition wears larger than the Garmin Instinct® E – 45 mm (50mm vs 45mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The Garmin Instinct® E – 45 mm is the slimmer of the two (14.2mm vs 14.7mm), so it slides under a cuff more easily.

On the wrist the Garmin Instinct® E – 45 mm feels lighter (48g vs 67g, case only).
