Thanks Eugene - I presume that the curators of MWO's serial number tables just need evidence of more than a few watches in a given range existing, then they'd update?
Yes. I’d take it you have one of the last 321’s. Since no archive it’s not going to update their charts... but if that range is unavailable...

You might want to recontact them and verify it’s lost not a stock response that it was for another watch.

No idea. As Foo2rama says, may be worth giving them a shout.

I am a little confused. It appears MWO already verify that 24m serial range as plausible for a 145.012 if the tables Eugene linked to are correct so I think you are already good there. It is the archive people you need to persuade, that may require a chat or if the records are genuinely lost it may not be possible.

I have seen enough to consider your serial correct and your watch original. As I have speculated before, during the 145.012 era, ie 1967-69, Omega were chucking in 321s and casebacks out of sequence. On another thread it was discussed how in 3 consecutive days in Oct - Nov 1968 Omega, according to the extract team produced a -68, the next day a -67 and the third Michael CollIns example for which I am not entirely sure of iteration but the -68 has a lower serial than the -67. Mine was made a day after Collins’s but is a few thousand away in numbers. Aldrins was only a couple of thousand lower but most sources consider that a 105.012-66. Of course since it is lost it is tricky to be sure.

It is messed up in that era. Perhaps they had a big box of 861s and 861 dials looming and kept finding stashes of 321s in the stock room!

Very well put, basically what I was eluding to (or at least trying to) in my first post, but lack of experience on my part perhaps watered down the message somewhat, not helped by the 'transitional' clanger...

My background is more vintage Subs, and the difference in date terms between the serial between lugs, and the case back date, can often be quite significant, particularly so on less popular models.

Within a year or so, I wouldn't rule anything out (in date matching / sequence terms) when it comes to Omega & Rolex of old.

Recent thinking is that the case backs got swapped in service. Unless it can be proved with original receipt. The extract does not list sub reference.

In the case of @padders eample above - is there any practical difference between a -67SP and a -68SP? eg according to the extract team produced a -68, the next day a -67 and the third Michael CollIns example - is the only thing different between the 3, that the -67 in the middle had a case back saying -67?

My understanding and my reading of MWO and SP101 suggests this, the only difference is the caseback number.

My own 145.012-68 is rather unusual in that it has a near unique 69-70 service dial (as confirmed by STS) but that is by the by!

I've seen some discussion about case back swaps during service, but the replacement case back had additional numerals - eg 145.022 became 145.0022 when the case back was replaced. Did that process start earlier?

It seems pretty unlikely to me that a series of -67 watches would go for service and get a new case back with a completely different reference... but then we are talking things that might have happened 50 years ago...

Not replacement necessarily.. but swapped between 2 watches serviced at the same time. Although it is plausible it got a new caseback at service and at least one appears to have been restamped with the correct sub reference.

145.0022 is the part number for the midcase post sometime in the 80’s. I believe all of those are first watch on the moon.

Most of the known 1450.12-68s are in the 26.55m serial if I’m correct ? Mine is

Mine also (26.554.xxx)

OK - I bought a -68 Speedmaster with what looks like a too-early serial number, as if it was from a 105.012 or even 105.003 (it's 24537xxx).

I applied for an extract and Omega quickly bounced it saying they didn't have the records; that and the fact that a respected watchmaker (who got the watch directly from the auctioneer) says it looks like it'd never been serviced or even opened, makes me convinced it's not a franken, but likely to be an errant batch of watches that were maybe using up old stock 321 movements with early serials, before the runout of the 145.012 and into the 145.022 with the 861 movement.

Is that credible? I'm sure I've seen 2 or 3 other watches being discussed that are marked -68SP on the case back, look like they stack up in other regards, but appear to have a serial number that is well outside of the expected range for a 68, at least if you look at MWO / ILMS or other well loved sources of knowledge.

If anyone else has a similar (24m - maybe even 2453xxxx as I know of 2 in that range) numbered -68s, please let us know for the benefit of the Speedy community...

Hello, yes! I have a 145.012-68SP that was a one owner from new watch purchased in Japan in 1968 by a serving Naval Officer and never out of his ownership until he died in December 2023 and the serial number on the movement is indeed 2453****! So, that is the 4th known example with these exact numbers so they must be part of a genuine batch produced from the Omega factory.

Agree, my 145.012-68 has the serial 26.55x.xxx

My 145.012-68 with an EoA is serial: 26.553.xxx
My 145.012-67 with an EoA is serial: 25.440.xxx

The Speedmaster 145.012-68 you are proposing has the serial 24.53x.xxx and the EoA was denied...

IMHO: everything said

No, not “everything said”…I have now come across another example (March 2024) of another 145.012-68 with serial number 24539871. That makes at least five known examples of 145,012-68 all with serial numbers beginning 2453****. Are you seriously suggesting that all are coincidentally serviced with these replacement movements or is it much, much more likely that there were a series of batch movements used from the Omega Factory in 1968 in originally produced 145.012-68’s?

It is difficult to affirm your statement in absence of an official Omega document.
Do the other 145.012-68 with serial 24.xxx.xxx you found have an EoA?

Cheers
