Parts list / Service manual for a Citizen 8100A

[croolis]

I have a Citizen 8100 chronograph in what looks like NOS condition except for the start/stop pusher not working .. the chronograph runs and resets OK .. When I gave it to the watchmaker he bent a part that made it work, but after a couple of start/stops it got bent again, so this part needs replacement. The problem is I don't know what this part is called, there seems to be very little available information about this movement.

If anyone has technical manuals or even an exploded view / parts list it would be really great.

thanks.

If the manual scans are too small, I may have larger sized ones personally. Post here if you can't read the numbers & I'll check my own database to see if I can read the part#s you need.

There are also schematics and parts lists in my chronograph article, here: sweep-hand.org/citizens-vintage-chronographs/

Scroll down past the info on the various models and you'll find the images.

Thanks Stephen, watchmaker just replied that previous scans were not legible .. Excellent article too the 81x0 movements from Citizen are in some ways even nicer than Seiko's automatic chronographs.
