Citizen 8110 (bullhead) chronograph module not working

Recommended Posts

Hello eberyone! 

I have been working on a really cool Citizen 8110 movement lately but I am having some trouble with the chrongraph module that attaches to the movement. I have assembled everything, as I think, correct but I am having trouble attaching the chrono module and when it finally lines up with everything and sits flush, the module doesn't work. The pusher cannot be pushed inward.  
Like mentioned, I have tried removing all tension springs upon assembly and having the parts in different positions on the chrono module but I am still having a really hard time aligning everything to make it sit flush. 

I will attach some photos below and maybe someone can give me some advice on how to attach the module easily or point out something I have done wrong. Thanks(:

I'm doing everything like the video but I just can't get the pusher to move. When not mounted on the movement, everything works great. Whenever I mount it on the movement, the pusher just seizes. I have tried for 4 hours to get it to work now but I just can't. I really don't understand it

    • After trials and tribulations, I got the balance spring working! Now I can move on to the disassembly. There's something preventing the watch from running. I suspect it was dropped and that messed up the hairspring.
    • I haven't been keeping a written log or hall of shame, but I can tell you that my early attempts to unwind mainsprings have resulted in two barrel arbors entering the ionosphere. Still MIA. I've launched but subsequently found incabloc and trior springs, a few yoke springs, and a third barrel arbor, but those first two remain elusive. (and one was from a ST36... not a small piece of metal, really)
    • I’m not shocked that nobody has been able to help me with this question. The Patek mainsprings are not in any Bestfit (or the like) catalog that I have ever seen.  The mainspring (even generic) is quite expensive to purchase, which isn’t surprising, either. The barrel ID is 8.7mm and the arbor is about 2.8mm. I’ll have to guess a little on the strength and length balance but I’m sure I can find something close. Based on the dimensions I provided, can someone tell me what size ms they would put in it? My new estimation is 1.20x0.10x11.5”
    • I spent some of my spare time, this last weeks, to set up a logbook system that fits me, helps me to follow my progress and my stocks and more. I also started a "Tableau de casse", a word game in french like hall of fame/shame, literally a table of broken 😁 One diafix on a Seiko Lord Matic : I spent time with this diafix to remove the jewel, and when  it was time to put it back, the diafix was blocked. I tried to move it forward without success. Backwards, sideways, then I forced it a little (too much)... I found some spare in china.   Extracting a scratched glass on a Seiko Lord Matic Deluxe (buying the right dies will help): First sprint put back in its barrel (almost, except one part...): From this broken one. The first time it's difficult to hold the winder and push the end through lunge... I hope I'll do better the next time!   And you, how do you manage your evolution ?    
    • For oiling the pallet stones or escape teeth i would need the 15 x loupe and have my nose pressed right up the movement in order to stand any chance of doing it without a microscope
