Forerunner® 230 (010-03717-40)
Garmin
Instinct 3 Solar Tactical Edition 45mm
The Garmin Forerunner® 230 and Garmin Instinct 3 Solar Tactical Edition 45mm share a near-identical 45mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Garmin Forerunner® 230 is the slimmer of the two (11.7mm vs 14.9mm), so it slides under a cuff more easily.
On the wrist the Garmin Forerunner® 230 feels lighter (41g vs 52g, case only).
