The back cover has detached from the body of the watch exposing wires. We are going to the Genus Bar. Has this happened to anyone else? UPDATE. Our visit to the Genius Bar proved to me, once again, that not all geniuses are created equal. I requested immediate replacement under Apple Care. No go. They insisted on sending it out to the depot for a decision to either repair or replace. One Genius had an interesting theory, however. He said that batteries sometimes start to expand--either pushing out the front or back of the Apple Watch. I will post again when we get more info from the depot. UPDATE #2. Apple came through, just like they usually do. We left the watch at the Genus Bar on Friday, and received a phone call the following Tuesday advising us that Apple had decided to replace the watch and we could pick it up. Now my wife has a shinny new watch and we are all happy again.
