Package included 1 x Cawono DZ09 Smartwatch 1 x USB Cable 1 x User Manual Notes: FOR iPhone SOME FUNCTIONS WILL NOT WORK: you can pick up calls, see the phone number, and listen to your music, besides all other watch functions like alarms, lost alarm etc. But it will not sync with your phone book so if you get a phone call the number shows up but not the person name, you can pick up and answer but it's not syncing with your iphones software. Some other functions that work on Android may also not work on your particular iphone. Just be aware, its a great watch even for an iphone, but you may not get the full 100% out of this watch, maybe more like 85-90% of functions which is still pretty good for this price iPhone did not support APP download!!!! Please don't connect the smart watch with charger directly, excessive current may damage the device, please kindly understand!!!
