The Citizen Astrodea moon age. The original watch was delivered with a 10x magnifying glass. There are a lot of tiny details and astronomical functions. There is still one problem left with the center wheel for the moon age, it seems not to work as expected. I will try to fix it.
I would like to link the manual, but the only one I could find is in japanese.
Update 12.05.2019: Rotation error of the age of moon wheel is fixed. Not so exact like my “.watch-version”, but now it works.
