Approach® S2 (010-01139-00)
Garmin
Venu 4 - 45mm
The Garmin Approach® S2 and Garmin Venu 4 - 45mm share a near-identical 45mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Garmin Venu 4 - 45mm is the slimmer of the two (12mm vs 14mm), so it slides under a cuff more easily.
On the wrist the Garmin Venu 4 - 45mm feels lighter (38g vs 52g, case only).
