TAG Heuer Connected Calibre E4

Tag Heuer

Status: Discontinued
Launch price: $2,150.00
Release date: Mar 1, 2022
Wear OS at launch: Wear OS 3.2

Most recent TAG Heuer Connected generation as of this writing (Snapdragon Wear 4100+, 45mm titanium case). No confirmed successor generation was found as of early 2026, though this could not be re-verified via live web search in this research pass -- flagged for re-checking in a future update rather than assumed current. Marked discontinued here per this phase's blanket historical-hardware treatment, though TAG Heuer may still be selling colorway variants of this same platform.
