If you want one of the "cheapest" gen PAMs, you should go for the 000 I guess. But better go for the 111 as it just looks better IMO. I believe that the 44mm PAM doesn't wear that big. I've got a gen seamaster 300m master co-axial with 42mm diameter and for me my old shitty 111 rep wore better on my wrist (I've got a really small wrist btw) EDIT: too late but I'm sure you'll have fun with your 111
If you're going for a gen PAM, just buy one that has not been repped to super rep level yet. Else you may find yourself getting the rep later and flipping the gen because there's virtually no difference between the two. I know some personal friends who've done it or were saved by the bell before jumping the gun on a gen PAM. Of course nothing beats the gen 100% but it's pretty close. Not Worth Buying In Gen or NWBIG.
