What separates these two

Two 2024 expedition watches: titanium bodies, sapphire glass, 10ATM water resistance, military durability ratings, offline maps and dual-band GNSS on both. The battery labels differ: the Enduro 3 lists up to 90 days with solar charging and 320 GPS hours, while the Vertix 2S lists ~40 days and 118 GPS hours (approximate). The Enduro 3 also lists a skin temperature sensor, SOS with live location sharing, Garmin Pay and a flashlight, none of which the Vertix 2S lists. On listed specifications, the Vertix 2S does not counter with a feature the Enduro lacks; what separates them beyond that is the case, 50.3 mm against 51, and a sun-readable solar display on the Garmin side.
