The Cogito Fit Lux is essentially the same model as the Cogito Fit smartwatches. They are analog wristwatches with �smart� features baked in. Underneath the chronograph, LED indicator will light up for specific notifications like emails, social media alerts, SMS, and more. All Cogito Fit models are 10ATM rated, which means they are able to submerge underwater up to a depth of 100 meters. They track fitness and health data too, as you�d expect. The Cogito Fit watches sync with Android and iOS phones via Bluetooth.
