Cool 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?
Yes, 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 of…
I 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.

Probably not expensive to implement, but if you’re building a lot of them, I imagine the ~4cents per unit (maybe more, just guessing) adds up fast.

Clearly the solution is to get Arizona to observe daylight savings!

(time sync over rf is super cool; I would be super interested if anyone has links to field surveys of time signal availability, potential gaps in coverage, and maps of said data.
