It's... JAPAN!!!
Japan in the back and Japan in the module. Any other country name on the watch. So it should be an old A-155w.
Old Tom, just a question... where did you find the information about this watch. I waste some hours trying to look for information about this watch and apart of some pictures from Casio collectors I did not get any interesting information.
Thanks!
Now it's time to spend some hours on my recently received Riquartz, Pulsar and Duward LCD's
