The G-Shock GA-2100 series was the most successful new G-Shock model of 2019. The all-black GA-2100-A1 (GA2100-1A1 in the U.S.) was the most popular colorway by far and sold out shortly after its release. In 2020, some U.S. retailers have received more stock, but the watch is still selling out very quickly, and it is only available sporadically.
Authorized Dealers That Have Restocked the GA2100-1A1 More Than Once in 2021:
For the U.S., Gshock.com is the only official retailer that we’ve seen the GA2100-1A1 in stock at in 2021. We’ve seen it in stock 5 times so far in 2021, and it still sells out quickly. It seems as if Casio is only selling it directly now and is not distributing it to other retailers.
