Maevit already gave you the link to the super reps 2013 topic. I must say that the Hublot Big Bang Stainless Steel V6 is very close to the gen, it's the best watch I've bought this year See this link for pictures of mine: http://www.rwgforum.net/topic/160367-hublot-big-bang-steel/
I've got the Transocean on Mesh bracelet, it's very easy to adjust there are links at the end of the bracelet you can get them out with a small screwdriver. Hopefully this will help you out
I've got no idea, this is my one and only PAM so I can't call myself an expert either. The 111 is also a beautiful watch but I suppose the thickness is similar to the 104.. As a whole, do Panerai make 40mm cases!? I thought the 44mm is the smallest they make? And to be honest, the first time I saw my 104 it seems small (I don't know what I expected), but on the wrist the 44mm case is perfect
