Speedmaster mid case

That was part of the concern for me, the description doesn't make a lot of sense (e.g. NOS but that doesn't match the photos; circa 1976 but made in 2003 etc). Also they don't come as a complete case as expected, and the seller said they wouldn't come in original Omega packaging or any other evidence that they are original parts. These factors, combined with the fact he'd already sold me a fake bezel previously...

When you get it, if you can post macros of the inside of the case where the pushers and case tube are, that will tell us a lot.

Dead thread resurrection time!
@Norfolk Did you ever get this midcase and what were the findings? Real deal or Chinese seagull case? I assume the later but am curious.
Thanks!

I think this is quite questionable, unfortunately.

If I look at the photo you posted of the inside of the pusher cap, along with the pusher screw, it raises some red flags. Here's a comparison I did of genuine parts and some fake parts that came in on a watch I received some time ago...



Note how well finished the surfaces of the genuine cap is, compared with the fake one. Here is a comparison of the pusher cap screws:



Again the quality of the machining is so much better on the genuine parts, and note that the thread pitch on the screws is different on the fakes. There are 6 threads total on the fake, and 8 on the genuine - yours have 5 or 6.

The outside of the fakes are slightly different as well - the cap is much flatter where you press than the genuine is:



Machining on the outside of the pusher tubes is also much better on genuine parts:



Looking at the photo of the inside of your case where the case tube is shown from the inside, that also raises some questions. I see no evidence of solder there. Here's a photo showing the area in question on a genuine case, and you can see where the solder is around the tube:



The only time I don't see this solder, is if the tube has been replaced. But if this is really a "NOS" case frame, then the tube should be the original from the factory.

So although not having the parts in hand, I can't say with 100% certainty that they are not real, I do have serious doubts.

Separate from what Archer points out, the lugs polished to me as well.

Sorry if the appraisals of this case are less than positive. If it helps, I've also had dealings with this seller where he's described parts as 100% genuine NOS but then been confirmed as completely fake.

Personally I think he describes these parts as old (e.g. NOS from the 70s) to cover disparities between what he's selling and examples of current genuine parts.

Resurrecting this thread to present the latest offering from the seller in question:

There seems to be a whole shopping list of issues here. But one thing that struck me is that he seems to have used the potentially dodgy bezel and mid-case (that he also sells separately) for the parts build. I wonder if the case back might be dodgy too?

Seeing this makes me a bit concerned about a proliferation of speedmasters with fake parts. He's been selling these bezels and mid-cases for years, and I'm starting to see them turn up in unrelated listings, usually for build speedmasters.

Following up on @Archer observations about these cases i handled one today, it came complete with bezel, pushers and movement ring sold as geniune from a reputable seller in EU, and it looked very very good. But i was concerned anyway as i found some damage on a listed as new case.
Here is what i found.

The caseband on the left side has a non fluid trajectary on the polished bevel lower end, like an almost inward angle, and is to thin compared to my Speedy from 2000`s . Hard to photograph but i gave it a try.




The easier tell is from the case back, if you look at the spacing in the word Mission you will see a gap, cant imagine it would have left the Omega factory like that. And the inside laser etching looks very thin to me but i have no good comparison at hand.



I found several listings with this on ebay and C24, but hard to see on some shots or not shown at all, and i only noticed it after i had one in hand and knew what to look for. Same as with the small "insert" in the body of the Hippo - to large and angular maybe ? The pushers looked good with a sligthly domed top, but i could not see any soldering with a loupe on the inside tube, it could be these are set with Loctite now ?

Anyway, bummer as these are out there and can fool most if not inspected seriously, and of course this case is now returned and seller informed.

If I look up the case on the Omega Extranet...the case specifications include this:

SOLDERED TUBE : Yes

Good to have a computeh ! Loctite on the fake one that is 🙁
