I'm not qualified in Omegas to give even a hint of an answer. I will say one thing, if its a rep its one heck of rep. Pearl is nice fit and finish is sweet, date wheel looks centered, dial printing looks good, etc. Please tell.
first thing I look at is bezel alignment. It looks good. I think it has pins not screws. Crown looks gen. Straight on shot would be good and normally the waves on the dial are more easily visible maybe just the photo. The bracelet is throwing me off but out on a limb and say GEN. Photos anyway. :?
The crown guard looks better then any smp 300m rep I've seen. The center opening of the guard appears to return all the way to the base of the bezel which is like the gen. Not sure if the tips of the guard (on either side of the crown) are quite squared enough like a gen though - hard to say. the crown itself looks a little strange, the bevel on the top of it looks too deep - but I may be wrong as I sadly have no gen too compare it to. Wish I did!
If it is a rep, you have to let me know where you got it.
it looks like a gen to me. On nearly every rep I have seen, the bezel pearl sits just a touch too low. It is in the correct position here.
One other tell tale sign is that the waves are usually centered on reps, and slightly of center on a gen. I can't tell how the waves sit from your pictures.
Yea I've looked for this rep many times and have never been happy with the results and came down to buy this and be a happy man or get a gen Rolex and sleep in the backyard until who knows when.
