Awhile back I found a brown bakelite "Owl Face" Zenith (Model L518Y) Deluxe alarm clock with an AM radio. Really pretty, like it had never been used. Somebody rigged the clock with a seperate AC line, so (I guess?) you wouldn't have to plug in the radio to use the alarm. Anyway, I've been using it for over six months and it has never failed to work. The clock keep better time than my Tag Heuer wristwatch. My wife still doesn't trust it, so she backs it up with her cell phone.
A shocking lack of faith, I say...
