·I don't think you know what you are looking at. There is already a spacer there - known as an enlargement ring. It's made of Titanium in this watch (220.12.40.20.01.001):

·Hmmm... I knew the 8800 movements were small when I tried on the current range SMP models and looked at the caseback to see the movement. It definitely looked smaller than the 8400/8500 that I have and I thought I was imagining it. But this definitely confirms it being small.
Here's the 8400.... Definitely looks bigger.
Here's the 8400.... Definitely looks bigger.

I think people need some perspective here. An 11.5 ligne (26 mm) movement is not considered "small" in the watch world by any means.
I've never heard anyone refer to a Speedmaster movement (861, 1861) as being "small" yet it is a 12 ligne movement, and at 27mm is only 1 mm larger in diameter than the 8800.
Is there as disparity between case and movement size? Yes of course and it's very common, which is why movement spacers (what Omega calls and enlargement ring) are also very common.
The movement clearly still does the job, so it's all good.
Cheers, Al

··Oooo subtitles!Thinking in historical terms, the 50X and 55X/56X and more recent 2824 and 2892 are circa 28mm so perhaps that is what we expect.

Well, setting aside the modern calibers you reference for a minute, Omega made plenty of smaller calibers in the past as well - the 710 series is also 11.5 lignes, and of course there are many smaller movements that were used in men's watches in the past. As small as the 625, which is only a 7.75 lignes (17.5 mm) movement.
Now to the 2824, and 2892 - these are both 11.5 lignes movements, so also 26 mm (actually ETA tech guides list them as 25.6mm).

·Probably cheaper, and they didn't have to develop a no-date version of the 8900, whereas the no-date 8800 already was in use by the 60th LEs, No Time to Die Seamaster, and I think the 43.5mm Seamaster 300m too. It all comes down to money. But my question is, why not spend the extra $0.25 for a spacer around the movement?
I think my highlighted screenshot (first post) gives off the appearance that there is no spacer, where on closer inspection there clearly is and has to be.

That's great to know, thanks Archer. How reliable are the mounting screws? Do they require inspection periodically or only at recommended service intervals?
Also, how thick/deep are such spacers normally?
Do any manufacturers decorate these spacers or, as, in this case, it's covered anyway, it seems like a waste of money/unnecessary?

·Might be useful
This is great. Is there a PDF available for this or is it copied from a dealer-only book or something?

·Yes it's from a book that OB salesmen are using.
Thought it might be. Is that the large hardcover one, about 1.5 inches thick?

··Omega Qualified WatchmakerThat's great to know, thanks Archer. How reliable are the mounting screws?
As reliable as any screw is. If it's properly tightened, it won't loose out any more than the screws that hold the entire movement together would.
Do they require inspection periodically or only at recommended service intervals?
No periodic inspection is needed. I have opened watches where the movement spacer has been screwed in place for many decades without coming loose.
Also, how thick/deep are such spacers normally?
Depends on the watch. There is no standard for this.
Do any manufacturers decorate these spacers or, as, in this case, it's covered anyway, it seems like a waste of money/unnecessary?
Some do, but it's unusual. Here is a vintage Vacheron with a movement spacer, and you will note it is also marked "metal" as the Omega one is above, but it's not decorated:
Note that was before service...movement was a bit of a mess.
Here is a ladies Patek that used a plastic movement spacer around the Cal. 16-250:
And here's a Panerai 104 with a fully decorated movement spacer around the modified ETA 7750:
Again people appear to be reacting poorly to the shot of the watch in the first post, but this is nothing unusual. It's not like we are opening the watch and seeing something as bad as this:

Indeed. And thanks for all that info.
That's reassuring to hear from someone who has been in more cases than most to reassure that the first pic is not unusual... and that plastic spacer on the Patek is a shock!
Is there likely anything between the movement and the caseback on the Railmaster?
