This is a demo unit of an Apple Watch Series 2, 42mm. It is a demo unit, so it cannot be paired. Please consider it as junk. You can use it as a watch to tell time. You can't pair it, so you can't use the apps. The battery life seems to be good. If you are okay with this, or if you can remove demo mode, how about it? ※Important This is a demo unit (considered junk), so please purchase only if you understand this and accept no returns or refunds. I cannot provide support for operating instructions. It will be shipped in a padded envelope.
