Sweet Spot2mm clearance. Perfect for sports watches - bold presence, no overhang.

The Garmin D2™ Bravo and Garmin tactix® 8 – 51 mm, AMOLED share a near-identical 51mm case, so wrist presence comes down to thickness, lug-to-lug and weight.

The Garmin tactix® 8 – 51 mm, AMOLED is the slimmer of the two (14.7mm vs 17.5mm), so it slides under a cuff more easily.

On the wrist the Garmin D2™ Bravo feels lighter (56g vs 92g, case only).
