This is not a wall clock but the best all around Digital reaadout clock from the Big Stores like WALMART for me by for has been this one...

This has battery back-up and has the self correcting feature. Has large readout and is always correct except when I cross a time zone which will require a new manual time zone setting. My communications type life style I live in requires the 24-hour read modes for my clocks...
Being OFF-ROAD here most of this one "really takes a beating and keeps on ticking" as the old infamous saying goes...
Here at the home front I use one of those Radio Shack large Digital wall mounted Digital 24-hour dispay that has all of the information you are looking for but again is a Digital Read out. Radio Shack 63-1438... Also hard to find a RADIO SHACK anymore as well.

Kinda hard to get all of this information from a standard old clock style faceplace..
My other big deal for the RV Trailer was one of those large display Weather Station Panels with digital clock and remote outside sensor made by LA CROSS WS-8015TWC... Very useful to have in the RV...

The really big issue for us was maintaining the clocks moving in and out of the Time Zones thing... I don't think my wall mounted clock that came with my 5th wheel was meant to be taken down all the time to get corrected haha Finally got all of the RV TRAVELING out of my blood and seem to do most of our RV CAMPING withing a few hundreds miles around the home base here in Northern Neck Virginia now...
