Hello fellow Citizen Navihawk watch owner(s), I have the c300 movement and the first battery died (many yrs ago) so i JUST put in a new one in today Feb 28 2016. The instructions i have found to "short (AR) terminal and (+) of the battery twice" are just not clear enough to me. I need much more detail in actually what the " + " spot i am suppose to push (it does not seem to be clearly marked as what to push !! ) and the terminology of "shorting" the AR terminal is not exactly explaining what i am suppose to do there either. Can you help me on this? Possibly speaking on the phone might be the fastest to explain this so if you send me an email directly we can work that........ or can someone just post a pic of the opened back and run an arrow to the exact points that get pushed? thanks larry

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:

Shorting AC and + of the battery usually involves finding the connector on the movement back plate that is marked as "AC" (or "AR" in your case?) and the upper side of the battery (wich should be marked with a "+"). I use tweezers to short (connect) them, but you can use anything that is conductive, like a paper clip or short piece of wire.

Edit: What he said.

Thanks for the replies. I was not seeing them til just now. Ok, NOW, i think i have the facts i need. I simply take a conductor (paperclip) and run it across from the top of the battery (+ side ) over to the closest contact next to the marked/stamped " AR " ... and touch it on and off those points TWICE. Is that correct?

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.

thanks again twall3. FYI, i'm fairly certain the c310 instructions for setting back to zero differ from the c300. They mention the mode hand being set to the top ( tme )

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

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.

Sir Alan, thank you very much for giving me a starting point. Just bought a C300 with a claimed to be just dead battery. Brought the watch to watch shop in mall and guy replaced the battery and somehow set the time on the inside of the watch. Got the watch back and noticed the LCD display was really dim. When I pull the (M)ode button and hold ABC to reset it, the display lights up nice and bright, but right after I leave the 8888's screen back to no visibility at all.

Anyways, you gave me hope. Going to order a spanner wrench on Amazon and hopefully fix the screen due to bad contact. Your help has been awesome.

Ohh this is my first post btw.. Hello all - Kevin from Long Island NY

My 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.
