15202st Variants
Hi everyone, I’m looking for some info on what the different Mark and Series differences on 15202ST mean. I can obviously see the difference between pre-2012 variants with framed date and AP at 12 and the present design, but is there any discernable difference or functional difference between Series J and K? And is there any difference between 15202ST.OO.1240ST.01 and 15202ST.OO.1240ST.01.A?
Thanks!
