This is a like new Fitbit Sense 2 with four authentic Fitbit watch bands S/M Size plus the M/L black band as well, authentic charger and 5 screen protectors. The watch is like new. These is a tiny chip in the glass that is barely noticeable. I switched to Apple so no longer need this watch. Watch has been factory reset and my data erased for easy pairing with your phone. Please check the phone spec requirements online. Fitbit works with Apple and Android phones.
