Watch Screen fell off - Super hot.

We don’t make any judgement about individual cases particularly as internet photos are no substitute for seeing the real thing. The potential cost can only be quoted by Apple after the watch has been inspected, so Contact Support and start the process. Apple will also check and consider any liability under warranty before they let you know their decisions.
