Was there any evidence of battery leak when you replaced the battery?
The display looks like this (when the movement is dismantled)
it is possible that something is preventing good electrical contact to the display.
If you can't fix this yourself, Citizen UK will for about £70.
Pmd youMy new watch worked for about 1.5 yrs (i only wore it a few times since i have 5 other watches) and then all i did was buy a new battery. All * i * can say is that i removed & replaced the original battery (absolutely no leakage) - resetting it is another process that i do not know how to do. My eyes now are not good enough to use this watch so i will be selling it. If you want it let me know.
