You do not have an atomic clock. Seiko does not manufacture “Atomic Clocks” for the $30 shelf in Target. You (and others here) don’t seem to know what an atomic clock is, or how it works, or what it costs!
Your Seiko is a radio clock. It’s probably got a crystal or some other normal timekeeping gadget, and the external WWV signal is decoded to properly set it.
“Atomic Clocks” are marketed to ignorant consumers who blithely use the term when the only external source is a radio station. The Stratum Zero clock may be atomic, but the caesium is not to be found on your nightstand.
No caesium atoms would be found in your Seiko, bro.
If you know more than someone else, that's great! By all means, share some of what you know, so the rest of us can learn. Just please do it without putdowns.
