The EDA (electrodermal activity) sensor tracks physiological stress throughout the day — a feature absent from most competitors at this price.
Comes with Fitbit Premium for advanced sleep analysis, HRV trends, stress management scores, and personalised health insights.
Unlike Apple Watch or Galaxy Watch, Sense 2 pairs with any smartphone and runs 6 days before charging.
The Ultra 3 nearly doubles the Series 11 battery life, and satellite emergency SOS works even without cellular or WiFi coverage.
More precise GPS tracking in urban canyons and dense forests — critical for trail running, mountaineering, and triathlon.
The 49mm titanium case and 3000-nit display make this watch usable in full direct sunlight and water depths up to 100m (EN13319 certified for diving).
