 All the technical info you want is there.  The 92 has a ETA 2892, which is a time/date movement (no date in this case) with a chronograph module added to it.  Current Navis are ETA 7750 based, which is built as a chronograph from the ground up.  Both are similar, and one is usually chosen over the other for sub-dial layout considerations (2892 is usually 3, 6, 9 while 7750 is 6, 9, 12...of course there are variations, but thats a whole different story...).  Also, the 2892 is generally the choice when more complications are going to be added to it.  
None of the 92's are COSC certified.
