Thanks to my friend for showing me these!
Here are the regular release Frogman, for release in June in Japan.
GWF-D1000-1JF & GWF-D1000B-1JF
Here is the love the sea & earth thread in case you missed it: https://forums.watchuseek.com/f17/lov...n-2967730.html
Since these are June, I would guess the Sea & Earth one would be around that time as well..
maybe more at Basel.. an official press release would be nice.
