Garmin Instinct 2 Solar

D2 Cloud-Optional — Full function with the router off.

The unplug test

The Instinct 2 Solar tracks GPS activities, records your runs and hikes, shows heart rate and stats on its own screen, and charges itself from sunlight with no phone, no Wi-Fi, and no Garmin Connect account ever created -- the owner's manual explicitly describes phone pairing during setup as something you 'can' do, not something required. Skip the app entirely and the watch still tells time, navigates, and logs activities to its own memory. What you lose without Garmin Connect is smartphone notifications, Connect IQ apps and watch faces, syncing activity history off the watch for long-term storage and analysis, and features that depend on a paired phone like LiveTrack safety tracking.

Why this tier: Garmin operates a real, named cloud service for this watch (Garmin Connect), so D1 (no vendor cloud at all) does not apply. But the watch's own Owner's Manual states initial setup does not require pairing: 'During the initial setup, you can pair your smartphone with your watch to receive notifications, sync your activities, and more' -- 'can', not 'must'. The manual's Phone Connectivity Features section describes pairing as something that additionally 'unlocks' notifications, Connect IQ apps, Glances, and safety/tracking features, without stating that GPS tracking, activity recording, or the watch's core timekeeping/navigation functions require it. Core function (GPS satellite navigation, activity recording, on-watch stats, solar-assisted battery) runs entirely on the watch. Vendor cloud exists, setup completes with no account, and core function works unconnected -- the D2 row.

Class A is primary (manual, FCC filing, teardown). Class B is corroborated community reporting. Class C is never sufficient alone.
