So you don't see many weight differences with the rep? I am increasingly addressed for the black dial, it seems to me the best in terms of color and black would also be the color I like best. Reading the whole thread I have some other questions: 1) Is black really the best? 2) Is the movement reliable (now some have owned it for 12/15 months)? 3) It does not cost like the gen (400 vs 4000) but it is not free, if you need a revision are there watchmakers who put their hands on it? 4) For $ 20 more you can buy a bracelet + strap, I could think of taking both but is it easy to replace them? I have seen that some users have dropped the Omega symbol from the strap, are there any news? 5) What are the things I need to pay attention to when buying it (it's the first purchase)?
I'll try to answer some of this based on being in a similar situation as you and having done a fair amount of reaserch but have yet to pull the trigger
1) black or white seems to regarded as superrep quality the other colors are off in some way but its probably negligible.
2) I haven seen one of these movements be regarded as problematic by anyone aside from concerns about replacement parts.
3) A lot of watch repair shops will service reps just make it clear from the get go but sourcing parts may be another matter
4) Get the both its pretty much the best chance you have as they're far more expensive after you buy. Most regard the rubber strap well.
5) Check your QC photos a few times as misalignment seem to be the only common problem and its your best chance to get the probelm corrected. Additionally consider taking it to a watch smith for service and to check the water resistance if you're really concerned with long term reliability.
