Garmin quatix® 7 Pro vs Garmin tactix® 8 – 51 mm, SolarSize, Specs & Wrist Fit Compared

The Garmin tactix® 8 – 51 mm, Solar wears larger than the Garmin quatix® 7 Pro (51mm vs 47mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The Garmin quatix® 7 Pro is the slimmer of the two (14.6mm vs 15.4mm), so it slides under a cuff more easily.

On the wrist the Garmin quatix® 7 Pro feels lighter (70g vs 95g, case only).
