You might look into GPS devices.  They aren't quite as cheap as the WWVB
> chips, but there are lots of them on the market.


Yes GPS receivers can be very cheap and self contained and much easier yo
use than those WWVB chips.  I have two of the chips.  I don't think they
work now that WWVB has changed format and even back in the day they only
worked for a few hours at night.  GPS is better.

But there is another good source for correct time.  Most people today have
WiFi in their house, at school and at work.  If the clock is going into an
area where WiFi  is available then it can connect to NTP.    If the clock
connects to WiFi you can save money and parts count by not needing any
physical controls on the clock for setting or to control options as all
that can be done from a smart phone's web browser
