Few things - first there's not a lot of information on the Omega Extranet (where people like me look up parts) for this series. But looking at the case numbers 1960342 and 5960342, both call out a dial that has a date window at 6, and I don't see a date on your watch in the photos above, so for me that is an immediate red flag.
Second, typically Omega quartz movements would have the Omega name and caliber designation somewhere on the movement. If not on the base plate, it would be on the coil cover, or sometimes on the circuit, and here is an example of a Cal. 1438 so you can see what I'm referring to - in this case it's printed on the circuit:
The circuit is also black, rather than blue, and I don't recall seeing a blue circuit on an Omega quartz movement before, so the movement is another red flag. In addition to help confirm this is not a correct movement, in the chart you posted above, where it shows the watches without date, the movements do not use a date, and here we have what appears to be a no date version of the watch, using a movement with a date - Omega doesn't do this generally.
So for me, this is at best a put together watch from what I see.
Cheers, Al
