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

Hi, Larry -
I have the same watch, but must confess that I've not yet had to replace the battery. Nonetheless, the shorting requirement is common to many digital. Take a look at this technical manual for the Citizen C310 movement (very similar to yours). The last/bottom figure on page 11 shows the AR terminal (it's the bottom-most of the four copper contacts directly above the "AR" marking on the back plate of the movement). Take a pair of jewelers tweezers (if you have them) and touch one end to the (+) side of the battery, then touch the other end to the bottom of the four copper contacts (AR) twice. You then need to set the mode hand to CHR (or better yet, set it to CHR before you start the whole battery replacement procedure) and pull out the (M) pusher button (bottom right pusher on the side of the watch) and set to ZERO. That should do it! Take a look at the PDF here:

Yep, and then do the resetting to zero function where you set the mode hand to CHR and pull out the (M) pusher button and set to ZERO.

Hmmm - interesting. Unfortunately our library of technical manuals doesn't seem to include one for the C300. I see that the C310 has a different LCD layout than the C300. On the other hand, it appears that the only difference between the C300 and the C320 is that the 12:00 subdial is 60 sec dial, and not a UTC time dial, and that it has a sweeping second hand. Anyway, the location of the AR terminal appears to be the same: http://thewatchsite.com/d1/files/Citizen Technical Manuals/C320.pdf
