Citizen Crystron 1976


Recommended Posts

Hi, I just wondered if anyone could point me in the right direction for a service sheet. Calibre appears to be 8700 quartz although I am no expert. I've found a replacement glass from Cousins already. Watch is supposedly not working although not received it yet (eBay purchase, £11 shipped). Some issues with date change on both the quickset and normal operation. Any advice on changing the glass (which way to push)? Thanks in advance for all help. Really looking forward to seeing that blue dial. Steve.

Hi Steve  I have located two PDF's attached for the 8701 and 8702.   Pretty poor reproductions but better than none  hope they prove useful

Thank you for those. I had a look at both of those and I don't think they are correct. They seem much more complicated and appear to be later movements, possibly ecodrive. Thanks anyway.

if you post a photo of your movement, we know what we are talking about here...the image from Ebay doesn't have to be the same as your movement?

Thanks, well it should be the same as that is the watch that I purchased. Anyway here is a picture of the watch in my hands now. Definitely says 8700A two jewels. Steve.

    • Unfortunately I'm not that lucky. I started on the train side and after I noticed the binding I pulled everything out except the driving wheel to rule everything else out. It still binds. I'm going to double check that the pinion is fully seated on the staff first, then if no joy I'll push the bridge jewel up a fraction of a mm. Fingers crossed!
    • Happy to have helped, great way to start the day with a win! 🥳
    • Thank you for the advise!! It worked. The setting screw was a lock/unlock to remove the rotor. 
    • I have that French tech sheet too, it is a little different than the English one (eg, it doesn't have the auto works diagram). BTW, it looks like you are looking up the case number in the 1979 ABC supplement. The 1974 ABC catalog does have the 3093 case. As you determined it takes the 1222-5 crystal.  When I serviced my President 'A' (which also takes that crystal), I was able to fit a 29.8 crystal from my DPA crystal assortment. Those are, in my opinion, a great deal. The assortment comes with 10 sizes each from 27.8mm to 32.4mm in 0.2 increments. I pretty much use them for any non-armored crystal that takes a high dome crystal. I think they no longer make them but Cousins has still has some in stock but when I bought them they were around $40 for the set and now they are around $100. Still, at 40 cents a crystal it's still a good deal. For the large driving wheel, I remember I once assembled the keyless/motion works first and when I placed the large driving wheel it was interfering with the setting wheel on the dial side as the teeth were not fully meshing and it wouldn't fully seat. If that isn't the issue I got nothing and am looking forward to see how you solve it 🙂
    • Not sure, but just looking at it, it seems like the screw on the right may be a fake? The one on the left may not be a screw in the regular sense at all, rather a 2 position device, I think you need to point the slot towards either of the 2 dots and one will secure and one will open. Like I said this is just my best guess looking at the pictures.
