Purchasing Navitimer A23322 vs A13322

[DVDA]

I am looking to purchase a navitimer with steel bracelet instead of leather. I have been leaning towards the A13322 simply because I like the dial placement but A23322 is newer and seems to be about the same price.

Therefore I was wondering what's the different between the two models aside from dial placement. Also what's the overall condenses on which is "better". Also I see A13320 " fighter" also but it looks identical to A3322, what's the difference?

Finding an excellent condition A13322 also appears to be tougher since they are older so A23322 might just be the default option, unless A13322 is the better choice.
