Why buy each?

COROS Pace

AMOLED display at 32g and $249

First COROS Pace with AMOLED — a vivid 1.2" touchscreen in a 32g nylon-band body, making it the lightest AMOLED GPS running watch at this price.

41 hours GPS, 19-day battery

16 more GPS hours than the Pace 3, with 19 days typical use. Best-in-class battery life for a sub-$250 AMOLED GPS running watch.

Multi-band GPS and voice features

Dual-frequency L1+L5 GPS for precise tracking in cities and trails, plus built-in voice pin recording and audio lap alerts — new for the Pace line.

Fitbit Charge

ECG and EDA stress in a slim band

Full ECG, electrodermal activity stress sensing, SpO2, and continuous heart rate in a tracker thinner than most smartwatches.

Google apps integration

Google Maps navigation, Google Wallet NFC payments, and YouTube Music controls — more useful on-device apps than any previous Charge.

7-day battery with GPS

7 days of typical use, dropping to around 30 minutes per GPS workout session before needing a charge.
