What has your research found? If you haven't done any, this is a good place to start. http://omega-constellation-collectors.blogspot.com/
Would need clearer pics of the dial to be sure
Minutes markers look variable but might just be the image
Not sure it meets the MOY test
Lugs are polished and have lost some definition
Do you have a pic of the inside of the case back too?
Agree minute marks not correct. Also, could be image quality but some fonts not right (first A in automatic and first t in constellation). Better pics would be good.
Pictures are not clear, but my gut tells me that dial is good. Not all genuine dials have a short marker at 3. Some do and some don't.
The movement has been very harshly cleaned at one time.
Case has been polished heavily, but not the worst I've seen..
Overall condition is below average, but looks authentic.
