Vintage 101.010 movement Mismatch?

Recently I acquired a mint 101.010, the hands and dial are perfect, lug looks very sharp, movement is in good shape as well

While Omega EOA returns they could not provide extract of archive...

I'm wondering if anyone took this movement from another watch and installed in current one, or there's some hidden history trick I don't know?

Hopefully the expert in OF could share your insights. Thanks!

It’s hard to see clearly on the pictures but is that a reference 101.010-65 with a 12 million serial?

If so that is certainly not correct as 12m dates about 15 years earlier than the watch

I used to wonder if a stock movement was installed in a newer watch, while per Omega feedback it's not likely.

+1... 12M is a very early serial for 101.010s

Thanks for your comments David and myatt.
Actually I'm trying to understand in what circustance people will swap a good condistion movement from another watch, giving this piece is in quite good shape I believe the movement should not be corrupted by water or moisture, and as we know French made Omega chrono has unique case, dial and hands. That just makes no sense to me.

Movements are swapped all the time when the original movement is too far gone to repair economically. It's not a waterproof case, so water could be the culprit, but honestly there is no way to reconstruct what happened 50+ years ago. It's disappointing, but obvious even without the Extract.

Still, it's a lovely thing ... you should enjoy wearing it.

Watchmaker's swapped 321s all the time back in the days, when they had more than 1 on the bench undergoing service. Frustratingly common.

The bigger question - the the EoA doesn't elaborate on - is for what reference is the 12M serial appropriate for? With the symmetric clutch, it could very well be an early Speedy or a 4-digit non-Speedy's. Somewhere a 2998 could very well be sporting the original movement for your watch OP - and wondering why the hell does it have a 20+M serial!

Thanks guys, I guess that's a mystery I'll never find out...
Anyway, still a beautiful piece and I enjoy it.
