Automatic not winding.
Manual also goes rough.
Rotor moves freely but it has difficulty pushing the spring.
If wound runs normal 42 hours.
Came back from Brazil (five years) , took all watches in airplane and many automatics now have difficulty? Can they have gotten covid?
Never had watch issues so exploring .
Others with issues.
Dubey aerodyn X2 this is the GMT alarm. Dubey Worldtimer works fine.
Citizens x2 bullheads, x2 8180 and the diver as well issues (not sure number is correct) issues, the Seiko 6139s x4 steady as they go....no issues
Omega coaxial all good.
Very upsetting. Let's focus on this one first. As here the winding is rough, the others this seems fine and don't have the glass back to validate .
Been struggling through a number of #31 movements. This particular one was bought as a "running" watch, but it's been anemic from the start with some 80° of amplitude, just no momentum at all. I've cleaned it, oiled it, checked it and repeated some 3 times now, with nothing seeming to help.
One thing I've noticed is that the unlubricated movement always sticks hard on the trailing palette pin. Give the pin or balance wheel a flick and the escapement wheel kicks the first pin out easily and then hangs on the 2nd. I've lubed the pins before (which is a bit tough) and this (along with other general oiling) gets it going with the poor amplitude, but never for long.
Could the pin be bent in towards the wheel? Doesn't look it. Hairspring seems nicely shaped. I've lubed both pivots of the balance shaft and attempted to remove end-shake, but that adjustable brass pivot is getting pretty mauled.
I'm really trying to avoid taking this movement apart completely. Any thoughts? Thanks!
So there is this timex automatic i found online from a reputable seller. I cant find much about it anywhere. Ive been looking for a timex automatic but already have a few watches that look like the marlin. This one is a little different and i like it. Any info would be greatly appreciated
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

Good job! A long time ago I bought a "set" of three old pocket movements for spare parts. But... decided to simply repair them. One of the movements was same as yours. Last week I finally replaced the broken balance staff. Obviously, someone previously already went through this exercise leaving hammering marks on the balance. After some truing & poising things look promising. Did you install GR6880-TB mainspring?
No, the balance doesn't have shock protection (at least, in my unqualified eye, it doesn't appear so - see photos). I don't believe the jewel in the bottom came out of the mounting plate. I just unscrewed that one screw, took off the plate, cleaned the underside of the plate (and the top of the hole it revealed) and put it back. I didn't mess with the top jewel at all.
Hi all I'm trying to repair this one for an old Viet Nam marine buddy, who said it hasn't run since the day his grampa gave it to him just before he deployed. What I found was that the upper pivot of the balance staff was gone along with the balance cock upper hole jewel was cracked and chipped. I was able to secure a NOS balance, staff and hairspring assembled, and lucky enough that all the jewels and fits were good. I added a new white alloy mainspring for the heck of it, cleaned and lubed everything. Assembled it and put some power to the mainspring to check it all over to find what I thought was excessive endplay. I took the balance back down and under the microscope to find it looks like the staff upper pivot(or the staff OAL) isn't long enough to fit, or reach into the upper jewel when assembled. Is that possible? is the hairspring collet not staked to the shoulder? (I haven't gotten that far). 1) should I mic the staff overall length and try and find a longer one? 2) I see there are stake marks between the balance cock and base plate seemingly to raise it up or for binding issues. should I blend those down flush? 3) should I attempt to find a different balance/bridge/hairspring assy. and replace the whole thing? it wants to run that's for sure and does intermittently, which, after all the work, is encouraging to me. I'm soooo close. Can I fix this? much obliged- Mike
