G-Shock U.S. may be releasing the GWBX5600-1 and GWBX5600-1A1 in waves, restocked next day after launch

Following their initial release and selling out on September 15, Casio America restocked more G-Shock GWBX5600-1 and GWBX5600-1A1 watches the next day on September 16. We had signed up for restock notifications on the GWBX5600-1 and GWBX5600-1A1 product pages and received emails at around 12:11 p.m. ET on September 16 stating that both models were in stock again, but they ended up selling out again on the same day. It looks like Casio may be releasing these models in waves, but whether it is going to be more than two days is anyone’s guess. Note that if you sign up for notifications and they sell out again, you need to sign up for notifications again for each restock. It might also be worth mentioning that there were instances when a sold out item at Casio U.S. became available again on the same day it sold out.
