I would venture to say that most clocks that have stopped working as well as
they did in the past would be because of an increase in interference levels due

old scheme.
You sure have that right re interference due to
modern digital lifestyle, David. My
always-reliable Casio Pathfinder watch updated
great until I added a Time-Warner converter in my
bedroom a couple of months ago. It updates fine if
the converter is unplugged, not at all if it is
plugged in. OTOH -- other electronics nearby,
including a Roku and old 9" CRT TV, don't impede
the update. So mostly the TW converter is
unplugged and I use the Roku for watching TV in
bed at night.
