Garmin Instinct® 3 – 50 mm, Solar vs Garmin tactix® 8 – 47 mm, AMOLEDSize, Specs & Wrist Fit Compared
The Garmin Instinct® 3 – 50 mm, Solar wears larger than the Garmin tactix® 8 – 47 mm, AMOLED (50mm vs 47mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Garmin tactix® 8 – 47 mm, AMOLED is the slimmer of the two (13.8mm vs 14.4mm), so it slides under a cuff more easily.
On the wrist the Garmin Instinct® 3 – 50 mm, Solar feels lighter (58g vs 73g, case only).
