Citizen 8110a chronograph lubrication

[CaptCalvin]

I can't for the life of me find servicing documentation or guides for this movement anywhere. Going with pure intuition I'm afraid is inadequate either as all the chronograph parts are completely obscured and I can't observe their operation. I know how everything goes back together but trying to figure out how all the parts interact while in operation aches my brain. The thing is couple orders magnitude more intricate and complex than a 7750. Can anyone help me out with all the lubrication points particularly with the chronograph parts and the clutches? Thanks a bunch.

Some links to manuals which will have lubrication instructions, and video which is split in many parts shows where to oil but in a different language, you should peruse them.

Personally I very rarely look at lubrication charts or even movement drawings. Lubrication is a personal preference item. I use mainly the moebius HP series of oils with 9010 for the cap jewels. I have had no issues using his method.

I appreciate the resources saswatch88 but I wonder if anyone else has anymore. I have seen these before and would like to know if there's anything more thorough. clockboy I have used pure intuition with many movements. It's easy when you can see how everything works or simple enough to mentally visualize. But with mechanisms such as in the case a chronograph featuring column wheel, vertical clutch, AND flyback complication it is really difficult to figure out how it all works and intuit where to apply the lubrication, especially when almost all the relevant parts are completely obscured and make observing their operation impossible.

This document does give some more info on the function of some of the parts if you haven't seen it

Did you spot that the pink document on this page has generic citizen chronograph oiling instructions near the end?

If you search eBay for Citizen 8110 pdf, then you can buy a pdf of the servicing instructions... in French.

I agree with clock boy, just oil the chronograph exactly how you would oil any other chronograph. The videos i sent should show the functions as he is re-assembling the movement.
