Help with Greens

[WANNAMILGAUSS]

Ok as my sig suggests I was looking for a Milgauss but have now seen the anniversary LV? and have a new search.

I have read and read but wow, confused with all the abbreviations and tech talk that goes over my head.

Are there different versions of this watch (not incl the newer hulk?) that everybody is talking about some sort of letter designation? How does this effect what watch to get?

Random serial number is a non issue correct?

I am in SOCAL and I see these prices from $5900-almost $9k and it appears that the accys included are the deciding factor on similar condition watches?


Thanks for the help and sorry if some questions have been asked before.

Thanks
Brian
