Just curious, but would opening the caseback matter at this point? It is modern caseback- lacking the serifs and has the globe engraving.

edit to add: if it was serviced by Omega, would they engrave the correct reference into it?

Ah I didn’t notice that. So the actual sub reference will be hard/impossible to determine.

Guess it depends what the OP thought he was buying. For me, there’s little of the original watch left and so I’d get no joy out of owning this.

I would like to thank everyone in advance for all the input.

Bring on more!

I am learning a lot.

I suppose the mid case could still be original (with a service caseback) but at this point does it matter?

It's an additional mark which Omega has added relatively recently. In this case, a clear indication that the case back is of a later date, making the identification of the exact reference quite a bit harder.

More details on this Globe logo can be found through a simple search here on the Forum. It has been discussed extensively, for instance here; https://omegaforums.net/threads/omega-aqua-terra-quartz-weird-omega-logo.29364/

thx ... I Googled also ;-)

So
- caseback : is not original (proof = ingraved logo )
- movement : is correct (proof = serial number and extract)
- case : can be new or can be polished (proof = not perfectly done but it is irl very good, new looking) <- still open question
- bezel : is not correct (proof = dot below 70, need to beside the 70)
- bracelet : is defenetly new (proof = almost no marks, skratches and nr) <- is this a genuine Omega replacement bracelet?

Movement is correct for what though? When we’re determining whether parts are correct, it’s in comparison with the other parts making up the watch. In this case many appear to be modern service items so you’re running out of original parts for it to be correct ‘to’.

Breaking it down, the best case scenario is that the movement, dial and mid case are original. However, the mid case could also be service. I can’t tell from those pictures. Also, although -74’s can have stepped dials, it’s generally beloved they represent the transition over to flat dials. As pointed out above, as yours appears to be a late serial and so may be more expected to be seen with a flat dial.

So, your best case is that the dial, movement and hands are original, but it’s equally as likely that the only remaining vintage parts didn’t start out together.

I have no record of a -74 delivered in July of 1976…

I have a few hundred extracts on 76’s and 74’s.

I think that this particular bracelet is newer than the watch, but quite similar to the original bracelet.

Already noted with a flag. Step dials in -74’s are seen in early production pieces not even mid 1975 and later extract dates.

with the new caseback, bezel and other signs yours would never be able to reset the benchmark for the last step dial delivered.

I’ve been documenting -74 step dials and the 2 -76 dials for years to better understand when the cross over was and attempt to find the true reason for step dial -74’s.

Case is a modern service part. Easily spotted by the angled curve profile of the non-pusher side, and by the caseback stamp (as noted in a previous reply).
An original period case from the 70's should a sweeping curve.


Here is what a mid case of a 145.022-74 with a 39.183.386 serial number (Oct 21, 1976 production) should look like



Here is what a mid case of a 145.022-76 with a 39.814.695 serial number (Oct 21, 1976 production) should look like



Here is what a 100% original 145.022-74 produced only 2 days prior to yours and only 118 serials away (39.182.738) should look like.

They have the same production date?

It's a shame Omega don't see the beauty in original parts that have aged gracefully, but I guess they'd make less money servicing them.

It's a very nice watch. I'd just enjoy wearing it if I was you. You could try and source a case back, but is it worth it? Plus, it will never be the one that came with it. Prices for parts are crazy and have taken most of the fun out of collecting.
