Hey all,
I'm new to the forum and hope I found the right subforum to post my question. If not, please feel free to move it to the correct place.
I tried the search function as well, but couldnt find anything.
I own a 1st generation Citizen Navihawk Blue Angles watch. Its been sitting in my basement for the better part of the past 6 years or so.

I recently found it and decided to check it out .. see if its still working.
Obviously I had to replace the battery, who knows how long it had been dead. After replacing the battery and resetting it, it seems like the digital display is not working properly anymore. I follow the manual, set the dial to TME, pull out the button and hold A, B, and C for two seconds. Afterwards I can realign the hands (not sure what the english terminology is). But I basically have to do it in "the blind" since the display is not working anymore. The watch itself seems to work normally, keeps time and all.
If I tilt the watch and look at the display from an angle, I can actually see the display displaying all crystals after pushing A,B, and C. But it seems to be very weak. When I exit the alignment mode, I cant see anything on the display, no matter what angle.
Does anyone have any idea on what might be the problem? I hope I explained my problem properly, English isnt my native language.

Please ask if something is not clear.
Best regards,
Michael
