this is tough to beat. Gave one as a gift to my Uncle because he once mentioned the "neat" atomic timing of some Casio's. I found this at under $50 and he has since used it in his daily work (he works in an outdoor capacity, not a desk job). He is a watch lover, fine Swiss time piece fan, so to please him with this was nice. A quality product which he claims hooks right up to atomic time without fail.
