Must admit I am seeing similar things with a few of my eco drives.

Nice to know that i´m not alone whit this problem in the this world :wisb:

 

Tip #1: NEVER leave an Eco-drive watch in complete darkness for an extended period of time. In spite of the claims of power reserves from 6 months to 4 years (depending on the model), Citizen themselves recommend a daily light bath. Keep your Eco-drives where they can receive a daily dose of indirect sunlight when they're not being worn.

Tip #2: Some Eco-drives are self-starting when the secondary battery is completely exhausted, some aren't. It depends on which calibre you have. For those that can self-start, it may require 3-4 DAYS of exposure to bright sunlight before they twitch into life. For those that don't self-start, you may have to do an all-reset before they start charging.

Secondary batteries can be damaged by being completely exhausted. You may have to have a new one fitted by a competent repairer (some models are soldered in -- it's not always just a drop-in replacement). But before you go down that road, do a reset, leave the watch exposed to sunlight for a week, and see what happens.

 

had the same problem with my CB0020-50, although mine didn't spend more than 2 months without any light at any time.
Cannot be fixed on mine, tried everything.
Even the secondary battery is non replaceable, mainly because the case back can not be opened, it's not a standard case back

 

As Time wrote about the caseback so is my watch also, if I want to get in house I will have to go in through the Glass/face,but how I get the stem out first I dont know

I´m not sure that Citizen will get my attention in the future.

 

Is it Citizen's fault that you mistreated your watch? hmy:

 

Well, in my case, I was able to track down the correct secondary battery, and the watch does open from the back, just not in the conventional way.
Is yours a monocoque case?
Why do you think you need to go into it from the front?

(oh boy, if this wasn't a watch forum, what I just said could sound pretty awful)

 

I've seen twice on this particular movement where the plastic main plate has cracked so the stem pushes in too far and hits the center wheel. On one of them it would run as long as I didn't screw down the crown, the other wouldn't.

 

kinetics are the future :grin:

 

I had a similar problem with this:




It wasn't in sustained darkness, but over a 2 year period it did spend a lot time in either a safe (early days) or a watch box.

Net result - it died and wouldn't charge.

I sent it off to Citizen Service centre (in the UK). They fixed and returned it free of charge. Great service.

 

when Citizen says that a watch has (for example) a sleep mode lasting 4 years, and no where in the manual does it say it must be kept in light, then yes, it is Citizen's fault.

 

what's a complicated citizen eco dive. never seen it in hong kong

 

The capacitor can be replaced. I just replaced mine myself. The case is monocoque so you access the mvmt by removing the bezel and crystal. You then remove the stem/crown by pushing the release tab (located on the edge of the mvmt at the 13 minute position) while the crown is at the run position then gently pull the stem out. This can be a bit tricky so a gentle touch and persistence pays. Be very careful not to touch and damage the exposed hands during this process. Then carefully lift the mvmt out and turn over and notice capacitor (typically Panasonic MT920 for Citizen (not MT920 for Seiko Kinetic)). There is a tiny pin hole on the mvmt at the bottom right edge of the battery. I used a push pin and gently used that hole and pin to lift the capacitor out. Then insert new battery orienting it the right way (teardrop shaped brass piece on capacitor bottom) and reassemble watch in reverse order to disassembly.

 

Raising the dead again.

 

I would read the manual. As mentioned previously, depending on teh model, some need a certain procedure to get them started again
