Hello OF'ers,

I'm thinking of making a offer on this one. I still need to do some further research. This 7863c comes with a valjoux caliber 7734 in stead of a 7732. I saw other ads of 7863's with a 7734. Is the 7734 also correct for this model? It should have a serial around 138x right? These are the only and best pictures for now.

Ah. This is why I love this forum. Strange that I did'nt find this thread. I've searched everywhere. So the 7863 did came with the 7734. That's what my research told me as well. But it's good to know others have the same opinion. Thnx!!

If you need more information then @SteveP is not just very knowledgable but a really nice guy to boot. He turns up over on this Omega side too sometimes. Your OF login and password are good for Calibre11 too if you didn't know, just need to type them in. Best of luck with your bid and then we can welcome you to the Heuer Heretic camp 😁

I would be very cautious on this subject. I would consider a Valjoux 7734 as wrong until I have solid proof.
There are only two people participating in this thread and the knowledgeable guy says it might be possible. The interesting bit is the other guy saying he turned down a 7863 because it had a 7734 movement, which could be the reaction of many potential buyers the day you need to resell it.
I have bought one recently, and I must admit it was difficult to pay so much money for a watch with such a movement. And I am talking about the 7732 ! Had there been any doubt about a 7734, I would have certainly passed.
That’s the little special thing it’s a 7732 (which nobody heard of) and not the 7734 you find in 200€ chrono.
It makes a huge difference considering rarity.
Now on the wrist it a great watch which gives me a smile.

I think solid proof in this hobby is sometimes a bit difficult. The near best thing is the collective experience and conclusions based on extensive research. I can not imagine that all the 7863's with 7734 calibers have transplanted movements in them. I did'nt count them but I think I can find at least 7 to 10 of them on the web where the ad mentions that the 7863 has a caliber 7734. And you can not find a lot 7863's on the web. So it's not based on what two or three people are saying but it's based on research and talking to people who have a bit of experience in the field (so to say). Is it solid proof? No. Is is the next best thing? Yes.

I'm going to see the watch next tuesday. So maybe before that time we have a few more opinions.

I am not saying anything definitive here, just trying to balance the opinions displayed here. In French we say : « The counselors are not the payers ».
Out of the 7 to 10 cal. 7734 you mention, how many really have one and how many are just described as having one.
I would ask knowledgeable Heuer people if they would buy a 7863 with a cal. 7734, instead.
I hope I will have helped you in making a wise decision.

Yes. Thnx. I appreciate your opinion. And your question is valid. All the ones I've seen on the web, except for one, were described. No pictures can be seen. So that's a problem. But still, the amount of descriptions of the 7334's, together with the picture on calibre11, is quite convincing.

I must say, doing the research is almost as interesting as buying and owning the watch.

Jeff Stein gives a range of 138.xxx to 139.xxx here http://www.onthedash.com/autavia-early-in-depth/
Who's going to argue with Jeff?

Even my Grail, the Skipperera of which there are now believed to be 20 known, ranged from 105xxx to 108xxx -- and those cases carried a 7753 reference rather than the proper 7754! "Borrowed" from the ordinary Carrera production and who would notice except for us >50 years later?

Pinning down 100% exact dates, movements and serial numbers is just impossible. I have a Zodiac (Heuer) 7721 of the same period which is always listed as carrying a Valjoux 7730 movement, mine has a 7733. There are just so many little oddities like this in the Heuer world. Given the number of suppliers to the likes of Heuer, who were really just the assemblers of the watches, trying to match up batches to be consistent would have not been the worth the immense effort. There was nothing there that the buyer could see.
