USED Huawei Fit 4 Watch Battery lasts you 7 days or more depending on your usage. It counts your steps and heart rate, has most sports exercises, is smooth to use, and receives calls with a very clear mic and speakers. It's a watch worth it, honestly. The reason for selling is I love old traditional watches and don't need this watch anymore. For me, it's a better option than Apple watches. Condition: Used
