Hi All,

   My son-in-law called this morning and asked if a Heuer Autavia he had found at a flea market was real. After a question or two such as does it have two pusher at say 1:30 and 4:30 and  crown at 9:00 he decided to bring it by. He paid all of $5.00 for the watch- guy who had it said battery was probably dead. I opened it up and it has the Heuer caliber 12 movement. The pushers had gotten out of sync and weren't working but I sorted that out pretty quickly. The watch has a good balance but so far it doesn't run. He asked me if I would fix it and I said that it would take some research but I could do it. I have been searching since then for an online parts diagram or other information without much luck. Do any of you guys know of any resource for service information on this movement? Now that I have started thinking maybe I'll start looking for chronomatic and see what I find as well.

 

Thanks,

Charles K

$5, now that's what I call a result! I hope you manage to get the information you require Charles.

Is this the right movement ?

On www.cousins.uk they have Heuer 12 PDF file available, im not sure if its the same but worth a look :)

Hi,

   Thanks for the info. I actually found what I needed when I searched Hamilton chrono-matic. I wanted to make sure the chrono plate was removable in one piece after removing dial and hands. It was, however things don't always go as you would hope. The set lever screw rung off in the set lever while trying to remove the stem. That was the bad news. Once I got everything apart I found that a part, oscillating pinion, at least that's what I would call it on a valjoux 7750 had been knocked out and was rolling around inside watch causing it not to run. As soon as I started removing the chrono bridge the watch started ticking. It appears as if the loose pinion is good and I can't imagine how it became loose. Maybe someone has worked on it before and couldn't get it positioned properly.

   Under the dial I did find a part that I'm not sure about. Under the date retaining plate there is a c shaped part with a tail on it The c shape fits under the hour wheel partially and the tail part extends under the date retaining plate. I was able to determine how it was positioned but I'm puzzled as to it's purpose unless it's just to keep the hour and minute wheels separated a bit.

   I did take a picture before I started working on it which I'll post later.

Nice watch :)  Here is a break down diagram for parts numbers if it helps :)

Here are some more pictures of the movement. Notice that it is basically the same movement as the Hamilton micro-rotor Mark did a service walk through several months ago with a chronograph module attached.

In case anyone is interested in the finished watch. I got the set lever screw in I needed Saturday. So I cleaned it and put it back together- twice. Got confused a bit and put dang set lever screw in backwards and didn't notice until I started to attach set lever. Just took it off my timing machine and it was running about +3 sec. I am attaching two more pictures, one of the second counter running and one where it's reset. I'm going to tell my son-in-law that I'll let him double his money on the watch real quick if he wants.

    • Thanks for this post MikePilk, I just came across a similar problem with an Omega 1022.  The problem I had was the seconds pinion spring was bent out of shape and did not even engage with the wheel properly, so the seconds hand was not moving at all. (no power loss though :) I removed the automatic module so I could access the spring and work on it. Once I bent it back close to the right shape, I experienced the same problem you reported about power loss.  Many tweaks later, and the seconds hand is moving properly again, with amplitude back to good numbers again. Cheers
    • After cleaning up the pivots, I made bushes on the lathe. At this point I've pressed in 6 bushes (3 sets) and the wheels turn smooth. What I can also tell you, is that I'm not looking forward to final assembly. Getting the pivots aligned seems to get exponentially more difficult with each wheel that is added.
    • Islands are interesting places to live depending upon their size and other factors. This is a bigger island and it has a bridge to get there at least on one end. It's also big enough that you don't have to go someplace else to get things typically. It can be a problem if you get a job in Seattle though. Yes I've known of people who commuted from the island to Seattle for a job and I don't quite remember how many hours it took but it took a long time. So basically islands are nice if you don't have to leave very often.
    • Thanks @JohnR725! Everything you say makes a lot of sense and is encouraging to read.
    • isn't it nice to have a decent case open or when the case doesn't want to be opened? In the case of a Rolex watch that supposed to pass specific water resistant testing you probably do need to tighten the back down. But they shouldn't be tightened so much that they risk stripping the threads out. Then the other problem that comes up is the gaskets can start to disintegrate and then getting the back off can be quite a challenge unless you have a really good tool and perhaps some penetrating oil to loosen things up. Yes really nice case marking. When I was in school we were taught to mark the cases and  the American watch and clockmakers Institute even had a? So if you joined at one time they would give you an identification number. They were explaining or giving an example of if the watches ever found in you have a unique number they can perhaps figure out the history of the watch or identify the body it's attached to for instance not that that probably comes up that often. So you got a unique number and even made a special metal stamp that you can purchase. It wasn't a super big aggressive stamp but still it left a mark in the back of the case. Then I heard from people at work on Rolex watches they were using a felt pen indelible but later on they decided that was bad because apparently the ink could release  chemicals although it seems like once it's dry that shouldn't be an issue. Then of course today was nice is you can keep computer records sealed have to mark anything at all I personally find it's best to leave no reference behind that you were even there. Especially when you have a beautiful watch that has no markings at all and now it has your scribbling all over it not good typically if there is a typical and watch repair?  a lot of minor repairs you don't need to do a complete servicing. But beyond a certain point you're going to have to take apart a lot of stuff you're going to disrupt the lubrication even if it looks perfect right now and yes you might as well just go ahead the service the whole thing. also in a watch like this where a lot of things seem to be going on the complete service would be better then you'll know exactly where you stand versus dealing with unknown mysteries for prior repair.
