Chytré hodinky Fitbit Versa 4 Graphite černé

The Fitbit Versa 4 Graphite Black is a lightweight smartwatch with a touchscreen and built-in GPS designed for daily activity and health tracking. It monitors sleep, heart rate variability and activity to provide a Daily Readiness Score that helps decide whether to train intensely or opt for recovery activities. The device is water resistant to 50 m and comes with a black band in S/L sizes; it runs on Fitbit OS and displays workout stats, navigation and payment options directly on the wrist.

Advantages

More than 40 exercise modes, including strength training and kayaking, are available and tracked with real-time stats shown on the watch. Built-in GPS provides pace and distance for outdoor workouts without a phone. Google Maps turn-by-turn directions and Google Wallet support enable navigation and contactless payments from the wrist. The thin, lightweight aluminium case in graphite with a comfortable black band is designed for all-day wear, including workouts and sleep.
