My favorite WWVB clock is the Junghans Mega Atomic Alarm Clock. I have several of them and they work almost anywhere (in the USA). The manual says to change the battery once every 30 days. Just for fun I wanted to see how long they could go without having to change the AA battery - two of mine are well into their fifth year. They have a large display and will tell you how many days since it last set. They can be easily be found for $20 - $30.

See:  http://www.atomic-clocks.com/juatalcl.html

...Or, you can get them on eBay for around $200.00
