In this demo, I demonstrate how the Apple watch functions when the iPhone is turned off. As it turns out, you can still access clock face/time/date etc, last synced, Calendar/Mail list, last reported weather, alarm, stop watch, timer, world time, play music last synced to the Apple watch, activity and workout apps, check phone app for your most recent received calls before your iPhone was turned off, and quite surprisingly if your Apple watch is still in the same area where you had your iPhone connected to a wifi network such as home, you can still use Siri and access/read your messages plus sending/receiving.
