Hi, mid repair of a rusted Omega Speedmaster reduced, first time working on a 3220. In hindsight not the best decision as It's not always clear if parts are suppose to come apart or not...anyway I've worked through most of that now and am left with one mystery part. Pictured below. It defiantly needs to come out, and it definitely needs replacing, but in the 3220 service doc I'm using it's only ever shown in place and it's not named, I guess its the operating lever / upper operating lever?

In the picture from the service doc it's the part at 4 o'clock with the lubrication point on it. This is the first step that adds parts to the main plate and its shown already in place.

The second photo shows the rusted part on the watch I'm working on

The last pic is just for context and shows the movement and it's rust.

 

Some my questions are, what is it, and how do I replace it?

Why omega didn’t include it in the service doc we’ll never know.

It's because under normal circumstances it's not a serviceable item.

Edit

Just realised that the 55.083 is shown in the Technical Guides. What documents have you got?

I had to do a similar rust mitigation project on an omega 1140 speedy reduced. Yeah it looks like an operating lever. The DD parts aren't particularly well finished I have noticed, so even trying to sand and polish this down might cause issues. And these parts are expensive!

    • 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.
    • That Island looks pretty good on the pics I found. Must be nice to live there. Welcome! Are there many watchmakers over there?
    • I believe so. I thought about it the last time.
    • Could you fit a sapphire crystal? My 'daily wearer' Breitling Aerospace is 22 years old and there isn't a mark on the sapphire crystal.  
    • Oh that's neat. I typically use a thin strap of rodico laid over the pallet fork to affix it to the upper plate but it can be hard to retrieve sometimes. And as I did more research, I may have just found your own earlier explanation: https://learntimeonline.com/forums/topic/potence-clip-for-full-plate-p-ws/
