In regard to your post, I am a bit confused by the calibre in the box it says 10 AK however you call it 10AKCSH are all 10AKs CSH. 1 other question I noticed their is a + as well O on the movmt when 2 symbols apear do you always the year of the later mark?

Thanks for the help!!!

The CSH stands for Center Sweep Hack (or Center Seconds Hack).
