Citizen 8110a chronograph lubrication


Recommended Posts

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.

    • that band is old as stated, there is a kit that pops up from time to time on selling sites for the repair of these type bands, some of this type are adjustable on a few links, one adjustable type allows you to align the round opening in the expansion slit [like yours] with the rivet to separate, but if yours won't come out then the rivet head is too big and will have to be done with some rivet removal and replacement, I suppose if you could make/optain the correct rivets that one could alter the said band, the tops/caps do lift off after raising the tabs....  
    • This is a watch from a friend who sent it to a neighborhood watchmaker for a battery change. It came back with the watch stem in a ziplock bag and the dial skewed 20°. The watchmaker told him that the stem was faulty and the watch cannot be repaired. I opened up the watch and found that one dial foot was broken off and still stuck in the movement, while the other was bent until it was flat against the dial. The stem could be inserted but it couldn't be pulled out to quickset and time adjusting positions. I did a full disassemble, cleaned and oiled the movement. But when it put in the battery, the second hand runs super fast. Like it gains 30 mins every hour. Any advice on fixing this problem? TIA.
    • I determined that the balance staff is rotating, not the roller table, so my second attempt at riveting was unsuccessful. I have ordered a new balance staff and will take measurements when it arrives. The balance staff i originally ordered (and now reordered) was specified as: Replacement balance staff: (A. Schild Caliber 984 1002 1021 1124 Original Balance Staff Part 723) so it should be correct. Measurements: (see pic below for terminology) xxxyy is a place holder until the new balance staff arrives. Lower pivot: Old - .08 mm New - xxxyy Lower pivot to balance seat: Old - 1.53 mm New - xxxyy Roller shoulder: Old - .42 mm New - xxxyy Hub: Old - xxxyy New - xxxyy Balance shoulder: Old - .86 mm New - xxxyy Collet shoulder: Old - .56 mm New - xxxyy Upper pivot: Old - broken New - xxxyy
    • Hello and welcome from Leeds.  We're here to help. 
    • I was just about to adk that, probably they have unnecessary waiting lists to make their watches appear more exclusive than they actually are.
