There are lots of clocks and watches that synch to the local time

believe it is WWVB that sends the signal and not WWV but the
difference is not relevant.

Not relevant? How so? The FCC would fine them if they misidentified so
there is at least some relevance on some level.

As far as I know there's WWVB and a station in Germany.

The cheapest most accurate clocks are the ones that use the AC mains for
a timebase.

Actually the clocks with the most accurate display would be those that
synchronize daily with a time standard. That would include Atomic
(radio) Clocks and PC Clocks.

Find me a PC for under $10. Same for an atomic watch. And there are
many PCs that wander 10 seconds or more between NTP updates. The
traditional synchronous clock is the champion for staying on the correct
time the best over an extended period of time, without a reset of some kind.

Try to pay attention sparky. The thread is about quartz clocks being sucky.
