Hi guys I’ve got a citizen eco drive fitted with a E760 perpetual calendar module   It was dead and the second hand positioned at around 7 o’clock ( needs recharging indication) sat it in the sun for hours with no change. Fitted a new capacitor and after hours in the sun it will mark time with hour and minute hand but second hand is still at 7. Looking at the citizen info for this module it does require a long charge and has no quick start feature, but it’s been ages now I would of thought the second hand would be moving in 2 second jumps at the very least. I’ve also performed an all reset but even this doesn’t change anything. 

Im wondering if there is anything else I can do or if it’s just a case of the module being US

your thoughts and advice most appreciated

Does the seconds hands moves to 7h or just stays there when you perform reset? In the latter case that would indicate something is wrong or stuck with its motor and/or position sensor, rather than truly indicating low charge.

Yes it just stays at 7 , that being the case is there anything I could try or is it a new module required ?

thanks Andy

You could try taking apart the entire module to clean and lubricate it, however there would be no guarantee that it would fix it, and if you don't have the necessary skills you may end breaking or loosing some parts. Not that it would be very serious on something that is faulty anyway.

BTW I suspect that Citizen doesn't sell spare modules and they may even not have one even if sent to them for repair.

Many thanks for that , probably best left then I haven't really played about with quartz normally just replaced the module as its usually  easier and cheaper, Cousins do the module but at around £75 + vat p&p etc i don't think its really worth doing , the watch isn't anything special.

Thanks again Andy

If you work with quartz watches gets yourself a "line free" box, discussed in various places on this forum. It could actually work in this case too.

Funnily enough I have got one of those and did try to spin it up on it very briefly but didn't go to mad incase it did more harm than good but nothing ventured nothing gained I shall give it another blast , whats the worst that could happen lol

I will give it a whizz and report back

The hour and minute hand spin round freely but the second hand doesn't budge , the seconds are pulsing on the boxes sensor but no movement at all from the seconds hand not even a twitch

      Gamblin Gamsol for cleaning?

      By joelcarvajal · Posted

      Thank you all for the replies!  Very informative! True enough, the Gamsol took some time to evaporate and does leave a residue. So not all naphtha are created equal!  Need to find alternatives then. i was able to try Hexane recommended by Alex and it seems great.  I wonder what the cons are?

      Yeah, I saw that in the tech sheet but I don't see how it can be adequately cleaned with the friction pinion still in place. I've accidentally pulled the arbor right out of the wheel once when I used a presto tool to try and remove it. Mark shows how he does it with the Platax tool. Those are a little too pricey for me so I got one of these from Aliexpress and I just push down on the arbor with the end of my brass tweezers. That usually gets it most of the way out and then I just grab the wheel with one hand the and the friction pinion with the other and gently rotate them until it pops off. Probably not the best way but it's seemed to work for me so far.

      Movement inserted from crytal side

      Thanks, Jon Sounds like a plan. Obviously I'll have the face on so do you think gripping with the holder will create any problems, but I will check in the morning to see how feasible it is but I assume it only needs to be lightly held. As for holding the movement instead of the holder won't be possible in this scenario as one hand will be puling on the stem while the other pushes the spring down. That was my initial concern is how the hell can I do this with only one pair of hands. All the other times I've had to remove the stem hasn't been a problem, apart from the force required to release the stem from the setting lever, but now I need to fit the face and hands its sent me into panic mode. If it had the screw type release things would be a lot simpler but that's life 😀   Another thing I will need to consider is once the dial and hands are fitted and the movement is sitting in the case I will need to turn it over to put the case screws in. I saw a vid on Wristwatch revival where he lightly fitted the crystal and bezel so he could turn it over, is this the only option or is there another method?

      Main spring

      By nevenbekriev · Posted

      Hi Jon, do You think that relation spring torque - amplitude is linear? I would rather guess that the amplitude should be proportional to the square of the torque. I had once idea to check it, but still haven't.

      I did not. I thought about it, but I had cleaned it in my ultrasonic, and the tech sheet shows lubricating it in place already assembled, so I figured discretion was the better part of valor. Although since I have to depth the jewels anyway, maybe I pull the pinion off to rule it out 100% as part of the problem. Do you know if there's a safe way to do it? I don't want to use a puller because it would push down on the plane of the wheel, and that seems like a Bad Idea. I thought about using a roller table remover, but I don't think I have a hole stake pointy enough to push it down.
