JJY Simulator

Time was adjusted to Tokyo time not US/ local time.

我是CASIO GW-5600J，时区选的是HKG。因为是五局电波表能接收日本电波。以往只能在旷野或者高楼无遮挡的地方手波。用这个软件，先把手机时区调成东京，后打开这个软件，音量调到最大，开始发波。然后手表GW-5600J打开收波，把表盘九点钟位置的背面对准手机喇叭，固定手表不动。一分钟左右看到收波信号能达到三格，一定要不动手表，等待短则两分钟长则五分钟就能听到成功收波的滴声。谢谢作者。

I own a Citizen watch that was released only for Japanese domestic market. The watch has atomic time radio sync, which unfortunately only works in Japan. After some research, I found JJY simulator which replicates Japanese atomic time radio signal and synchs your watch to your phone’s time. The app worked great, it is a very simple and straightforward process. My watch synchronized within a few minutes. Make sure that the phone’s volume is at maximum and place your watch close to your phone’s speakers.
