Replace a manual 611 movement with a comparable automatic movement?

So in typical innerweb forum style, instead of 1) answering the question or 2) not saying anything and simply moving along....80% of you chose to uselessly chime in with your $0.02 that I didn't ask for or need. Kewl...

It is your watch, you can do what you want with it. The point of this forum is the discussion and appreciation of Vintage Omega watches. It is not a service to provide answers to questions. From that perspective, I stand by my original post.

i totally agree with the above…this endeavor seems counterintuitive.

However, to answer your question: A 565 may fit the dial but it very likely will not fit the case. Most of the manual wind cases (with a few dual referenced exceptions) don’t build in enough clearance for the thicker automatic movement. From what I recall of the SM 600 case, an automatic movement will not fit.

Personally, I wouldn’t recommend you attempt this.

To the OP,

Your question was pretty well answered in the second reply to your opening post which I have quoted. It can’t be done! Get off your high horse, and listen to reason! There are none so deaf as those who refuse to hear! No, wait! Go ahead and try the conversion. Only way you’ll learn.

I love manual wind watches over all others. Makes me feel needed to wind a watch as part of a morning ritual. If that is watch nerdy-ness extremism then so be it.

There's no good reason to cobble together a half baked watch if an automatic is deemed necessary. Obtain satisfaction through acquisition of a good vintage automatic watch. It's a better use of money and both watches wll thank you.

Same, I have a project watch with winding weight removed and barrel replaced with a manual barrel for the "stop", outside diver watches auto seems like a gimmick

However Omega's autos are pretty impressive, usually there's the power reserve or movement issue paranoia when an auto watch stops, with Omega's 560/750 series movements, it's usually 1-2 days with 1-2 hours of wear

Also it's not enough for a movement to accept a dial, the case and crystal need to accept the dial too, they are all different sizes and shapes

It's a forum and threads are subject to debate and discussion. If you're going to initiate a post on any hobby forum then you have to be tough enough accept comment by all comers. Or, would you prefer that we all get in your thread only to voice approval, slap each other on the back, have a group hug, and sing "Kum ba yah" together over your efforts to jury rig a watch? You don't get special moderation privileges over your own thread and sarcastic scolding isn't necessary. If you don't like that, then ... tough!

I have a vintage Seamaster 600 date (136.011) with it's original cal 611 manual movement. Is there a comparable automatic movement from that era which it could be swapped out for without any real modification? Maybe a 565? I'm spitballing here and could use some expertise!

At the end of the day I have a rare dial and I wanted to put it to better use on an automatic. I suppose a better question would have been, "What movements will accept the dial of a 611?" That's it, that's all. But you all probably would have chastised me for that too all while refusing to answer the question. ::facepalm1:: 611s are a dime a dozen so I'm not ruining history. I have plenty of other all original pieces laying around to impress the great grand children with one day 🙄

These are two different questions with different answers.
As much of the base movement is similar I assume 611 and 612, plus the 56x date autos may fit your dial.
Whether they’ll fit your case is a different matter - They won’t, as auto cases have a domed rather than flat caseback to house the rotor assembly. You’d have to confirm that a 56x movement could take your dial, then transplant it wholesale into the auto case. However, not all 56x auto cases will fit your dial.
I assume it’s trial and error or you’ll need to get the diameter of your dial and use Google to find other auto references with the same dimensions.

While I don't condone this kind of "engine swap", I have seen it done with relative ease on early 60's Seamaster 30 manual wind models. The case back style is similar to automatic case backs of the same era.

That's what I would worry most about if I were the OP. In the process of trying to find an automatic movement AND case that fit the dial, the more you try, the more you risk damaging your rare dial.

Nice attitude there. Has it occurred to you that your case isn't designed for a movement as deep as the 565 or 552 or whatever? You will need at the very least a dished caseback. If your basic case was ever fitted with an auto option maybe you will find a back an maybe retaining solution to work, then you can worry about hand stack height, if it wasn't you might be SOL but you know what, the best advice you have received so far is that you chose to pour scorn upon: sell it and buy an auto. Then your dial will be right. Feel free to tell me I am an idiot too.
