I am not to sure about the worldwide release of these G-Shock, but these will be available in Taiwan next year 1st quarter. I think the GA-100 is a brand new G-shock. Not much information on these as I was allowed to take photos but did not have time to read up about it. Should be able to find out more next week when I come back from a family vacation.
Different versions of the GA-100.
A blue Riseman.
A blue Gulfman. I suspect this belongs to the same collection as the above Riseman.
Some new DW-6900.
A green G-6900. I believe this belongs to the Green Earth Series.
This G-5600 is also from the 'Green Earth' series. I stand corrected on the series. I do know these watches will come with a special box.
