Full ECG, electrodermal activity stress sensing, SpO2, and continuous heart rate in a tracker thinner than most smartwatches.
Google Maps navigation, Google Wallet NFC payments, and YouTube Music controls — more useful on-device apps than any previous Charge.
7 days of typical use, dropping to around 30 minutes per GPS workout session before needing a charge.
L1+L5 dual-frequency GPS for precise tracking in cities and trails, paired with Garmin's most advanced heart rate sensor — adding skin temperature monitoring over the FR265.
A first for this price tier — take phone calls, use voice assistant, and hear Bluetooth audio directly from your wrist. A meaningful upgrade over the silent FR265.
AI-powered triathlon training plans that adapt to your swim, bike, and run fitness — a key differentiator over the FR265 for multisport athletes.
