When your race lasts three days, your watch needs to last longer. The Enduro 3 runs 36 days in smartwatch mode and pushes toward 90 with solar charging through the sapphire lens. The transflective MIP display is the reason — it costs you AMOLED brightness and buys you weeks. Built for ultra-marathons and FKT attempts where a multi-day GPS session is a realistic scenario, and the first Enduro to carry Garmin's ECG app.
