What's the difference GW-7900KG-3JF and GR-7900KG?
GR-7900KG is from which country?

Hi and welcome to the forum!
GW - solar and atomic
GR - solar only
It's not possible to tell from the model number in which country the watch was made (the "JF" in GW-7900KG-3JF only denotes the target market - in this case Japan). But it's either Thailand, China or (less likely) Japan.

cheers, Sedi
