Approach® S6 (010-01195-00)
Garmin
Instinct® 3 – 45 mm, Solar, Tactical Edition (010-02934-50)
The Garmin Approach® S6 and Garmin Instinct® 3 – 45 mm, Solar, Tactical Edition share a near-identical 45mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Garmin Approach® S6 is the slimmer of the two (14.2mm vs 14.9mm), so it slides under a cuff more easily.
On the wrist the Garmin Approach® S6 feels lighter (46.6g vs 52g, case only).
