Citizen Crystron 1976

[steve1811uk]

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.

If I am correct these had a 8600 caliber(8650B)...

Picture on eBay suggests 8700A

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.

Dial also indicates 8700 but cannot find any record for this in my files.  I even checked back via citizen battery requirement document (attached) and 8700 is not listed there either.

if you post a photo of your movement, we know what we are talking about here...that is the easiest. I also read the somethimes have a 4-7100

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.
