La Crosse atomic clock model #WT-3143

There is a nut on the shaft that holds the hands. It has loosened. You will have to disassemble the whole clock out of the case to access that nut

If you have not talked to La Cross and if you continue to have the problem, most likely it may be a signal problem. I had a similar
problem with an earlier model and found that it only worked on
the west facing wall as the signal is coming from WWVB which is the NISTtime signal radio station near Fort Collins, Colorado. Get a fresh battery, reset the clock, put it in a west facing window and leave it overnight. If it doesn't work, contact La Cross as above post.

It sets itself. You just tell it the Time Zone. http://www.klockit.com/PDFs/lacrossemanuals/AnalogWallClocks.pdf

Check both of these

Daylight Saving Time Automatically Updates (DST) (On/Off Option) applies to both USA and UK

U.S. Time Zone Selection: Eastern, Central, Mountain, Pacific (applies to USA only)

Sounds like it is not picking up the radio signal.
Try placing it in a window overnight where the radio signals do not get obstructed.

When the battery is installed the second hand will advance eight seconds (2 seconds per step x 4 steps). The clock is now searching for a signal. For the initial setting it is recommended to stand the clock in an upright position near a window. Within five minutes the clock will either receive the WWVB signal and set itself to the exact time, or it will determine that the signal is not receivable at its current location and time of day. If a signal is not receivable it will fast-forward the hands to the 4, 8, or 12 o'clock position and search for WWVB each hour until a signal is received. If the time is manually set the clock will continue to periodically search for a signal and automatically reset the hands when the signal is received.

I'd say you have a lemon.
