Getting more out of an Apple Watch.

It only works when something is covering your face, and the watch must be on your wrist and unlocked. Setup, and what it will not do.

Apple's own method: water and a lint-free cloth for the watch, mild soap on some bands only, and never a soaking for leather or FineWoven.

watchOS has no screen recorder. Mirror the Watch to your iPhone, then use the iPhone's Screen Recording. Screenshots work on the Watch itself.
