I open this thread to archive works on Citizen 8110A Bullhead. I purchased this watch in poor condition as You can see on the photos.
Cause I have serviced few chronographs in the past I decide to try restore this watch. Maybe is not ractional from the economical aspect but we do this because we love it So let's open it.
Hands are in good condition (required repaint and relume) but the dial has broken legs and tachy scale is faded :/ I think it's really hard to find orginal and there is no gold aftermarket replacement - sad. Look at the movement.
Gosh, what a dirty place It needs good cleaning and oiling. But the biggest problems are this.
Broken post on main spring bridge and missing rocking bar core and screw in gear train. I need to find replacement.
While I'll be working on movement the case and pushers are send to renew - putting new gold plated coat
Hi all, I'm new here, but have been watching the videos on YouTube for a while now, and used them to educate myself on the nature of mechanical watches. Thanks for the great videos Mark! You helped take the mystery and fear out of these works of art.
I have a Rotary Monza I am fixing up. I disassembled the barrel and removed and cleaned the mainspring. I secured a copy of the parts list and it shows that as well as the mainspring, there is also a Brake Spring (part 775 on the picture). What is it, and do I really need it? Certainly Cousins does not sell it. I googled AS 1902 brake spring and ONE result came up of a Russian watch forum discussing this item. Apparently it is thicker than a normal spring and it seems to have some sort of bent over feature on it. Can I just make one using the old mainspring? If so, how long should it be? Is it really necessary?

Hello there watch fix fans. Here's (I hope) an interesting one for you.
I have this beautiful small ladies 'Fero Feldmann' Swiss-made watch - it came in a bag of "used and to be repaired" watches.
From what I can see, the mechanism seems in very good working order. Just a slight shake and it goes and goes. There is no strap, but that is not the issue here.
The problem is the stem and/or crown. As you can see, there is definitely no crown. But I am wondering about the stem.
The watch does have its case and edoes have, as you can see, a hole where the stem and/or crown will/should fit in.
There is something which appears to be some kind of part-stem at the 3 o'clock position.
Using tweezers I can pull it out and push it back in quite freely. A very small screw on top holds this "stem" in place. I think you can see, in ths second photo, how this "stem" attaches to the rest of the movement.
Clearly I need to attach a crown. BUT what about a stem? A stem extension? Or one of those crowns which has an extended stem-like attachment which should fix onto this current "stem" in this watch?
Yes, the watch face is somewhat scratched, and the minute hand is a little bent at the top. You may say it is not worth my while trying to get this fixed. But I just SO MUCH like this little watch and would LOVE to give it life again! It clearly IS still "alive" - though I'm not sure if it is a mechanical wind-up or an automatic. The latter of these seems to be the case - as I said earlier, a little shake and the mechanism goes and goes. PErhaps with a little oil (and lots of encouragement) it can be made good.
So my main question - what kind of stem/crown to attach and how to do it?
Fantastic! You did a lot of work on this but the results are worth the effort. Great pictures and I love the little arrows showing where to oil and what oils to use. It will be a very helpful reference to someone starting on their watchmaking adventure with this movement.
