[Product Information]

Uses a standard cell battery (CR2032- included) There is no re-chargeable battery. Comes with 2 interchangeable bands. The silver have a brown rubbery band and the black have a black rubbery band. Although the metal band can touch the water， a long time or will be oxidized， in order to protect the appearance of metal strap， my suggestion is need to put on the rubbery band when swimming.
"Activate Pop" mean， Do not need any operation，just connect the bluetooth with your phone， and In the personal information you can set name， gender， age， height， weight， change the unit of measurement (nice) and set an exercise goal. ( number of steps you would like to take each day.)

Set your camera on a tripod or something and you can shake the watch or tap on the watch screen to take the picture. The watch does not take pictures- just your phone. This is only a remote for picture taking.

You can set reminds on your phone for notification purposes. the one drawback is that you can’t tell the difference between when you are getting a call or text.Because there is not digital screen you can’t check the information from your watch- have to pick up your phone to see. So it’s a nice feature but is definitely more useful when it is on a digital watch face.
