Women's Citizen Quartz dive watch.

[napes]

I'm new to working on watches, so please assume I know nothing!

I bought this women's Citizen dive watch for my wife. Hoped it would be a simple battery replacement, dropped a new one in but no movement. (The pic shows the old battery in place)

I did notice what might  be corrosion around the larger brass screw at the bottom of the image. I'll double check the new battery voltage just in case it has expired. 

Is there anything else in the pic that looks dodgy?

And should the movement be dead, are replacements for this era and model hard to come by?

Thanks in advance for any suggestions.

Is there any signs of life from the seconds hand with the new battery

These movement are long since discontinued and think you'll be lucky to find a direct replacement.

There could be an alternative but this would require further investigation.

Thanks for the reply AndyGSi.

No sign of life from second hand, though I'll drop a new battery in tomorrow just to be sure that isn't the issue.

Hi having checked the battery. Got to be around 1.55. V.   I would try it in a line release machine/ pulse checker. On. EBay around £30 . Line tease is incorporated in these gadgets.  The idea being  if you have a sticky movement (old oil) it drives the mechanism at faster revs than normal.  Before doing this apply a little naphtha (lighter fuel) to the visible bearings.    NOTE. This will rotate the movement and free it up then refit batter6 and try again. If the watch starts up ok remember it’s only temporary and the watch will need a service.  Fresh oil and a clean.

It could well just be dried up oil that's "set" whilst it's not been running, though some quartz movements need a couple of points shorting to reset the IC and start it working properly again.

Have you tried setting the hands? If it is only just sticking, moving the hands back & forth may rock the gear train slightly and kick it back to life?

Thanks @rjenkinsgb - gave that a go after dropping in a new battery, but still no luck.

@watchweasol Remember seeing pulse checkers on a couple of vids - cheers for the reminder. Will see what is available here in Aus

 As said, apply naphta to  visible bearings and  remove the battery to  gain access to couple of palstic gears in gear train, use a tooth pick  to turn them, to unfreeze the train. 

Submerging  the whole movement in naphta for a couple of seconds wont hurt it.
