#2Great technology, works fine, at least 10-20 years old now.

#3I have a wall clock that syncs with an atomic clock in Colorado, which was cool at first but I live in Arizona now which doesn’t observe daylight savings so it’s often wrong by an hour now.

#4I have a citizen watch with this. Tends to keep time just fine. Though so did all my other quartz watches until the battery dies

#5They misspelled Mainflingen, where the German DCF77 transmitter is located, as "Mineflingen", which is basically spelled phonetically (for English speakers).

Yes but perhaps it reminds you of fond memories? Or just makes life a little more interesting - "Hey, dentist, sorry I'm an hour late!"

Time over radio has been a thing since 1927!
"A radio station at Rugby was first operated by the Post Office from 1926, with the call-sign GBR. From 19 December 1927, it broadcast a 15.8 kHz time signal from the Royal Observatory which could be received worldwide. It consisted of 306 pulses in the five minutes up to and including 10:00 and 18:00 GMT, with a longer pulse at the start of each minute. "

#8Cool to have this multiband technology, but what about the southern hemisphere? Assuming they have time signal transmitters, too: Do watch manufacturers have different SKUs that can receive signals in the southern hemisphere? Is it possible to have a watch that receives these signals truly worldwide?

#9Yes, as others have stated this is an old technology. I don't really understand why this is not more common in the modern day. it's not really that expensive to implement and they did it with analog chips back in the day...
Why do we have to set the time on our clock radios or on our microwaves or whatever? Why don't they just always use this Tech. I don't understand. All you have to do is allow people to store an offset for the time zone, and RTC issues are a thing of the past.

It's easy enough to implement decoding and there are packaged antenna (ferrite rod and coil) and conditioner (auto gain amplifier with Schmitt trigger output).
