Pametni sat Fitbit Sense 2

The Fitbit Sense 2 is a feature-rich smartwatch with a digital touchscreen and integrated GPS, offering advanced health and fitness tracking in a lightweight, water-resistant aluminium case with a white S/L band.

Heart monitoring includes continuous heart rate tracking, on-demand ECG for atrial fibrillation assessment and irregular rhythm notifications. Daily Readiness Score combines recent activity, sleep and heart rate variability to help decide whether to train or recover. Built-in GPS, water resistance to 50 m and compatibility with Google Maps and Google Wallet add practical everyday functionality.
