~ 1 year of light use. Works great for everything from message notification, tracking, heart rate monitor, all kinds of sports to being an cool little bluetooth mp3 player while running. Everything is in perfect condition (only the strap can be seen with some slight sighs of being used). Compatible with both IOS and android. Original packaging with the watch, charging dock and charging cable. I bought an additional charging cable and have included as a gift. Pick up from stanford west apartment. see the link below: https://downeystore.com/products/xiaomi-amazfit-smartwatch-english-version?_pos=1&_sid=70fd9ddb7&_ss=r
