iOS Watchkit: Is it possible to show static UI in Watch when app is not reachable?

Question

Can we show some static UI in the watch when iPhone is not reachable to AppleWatch?

Suppose I forgot my iPhone at car seat , and when I move from car, Is it possible to shows some static UI in AppleWatch that you forgot your iPhone?

The end result is that if iPhone is unreachable, the app will not function. There is not a way to currently cache information to keep it alive or seemingly so.

Actually you don't have to do anything. I noticed on the real Watch, that Apple will present a default "iPhone unavailable" screen in case the iPhone is out of reach. Similarly, Apple will also present a default "flight mode" screen when the Watch is in flight mode :) . See attached screenshots.
