ASUS ZenWatch 2 Smart Watch Android Wear This watch can also be used with an I-Phone. I am not sure about phone call compatibility with certain phone models and such. This is for a pre-owned watch in good condition. The battery may not hold the same charge that it did when it was new. I tested the battery and without doing anything, making calls or texts or fully using it, it lasted about 8 hours. (This phone is designed that you can replay the battery if you have the correct screwdriver.) This watch has been lightly used and the brown strap in in good condition but does show light signs of wear. Please see pictures and ask any questions. What you see is what you get. All offers welcome.
