Hoyen,
I also noticed that Breitling doesn't bother with being a "chronometer"
either.  Also, some Rolexes are not chronometers.  The "date" model is
not.  The "datejust" model is.  The thin dress watches are not.  I
believe a watch must be self winding to be accurate enough for
certification... this keeps a constant tension on the spring.  Like you
said, being a chronometer is marketing hype anyway when a cheap Swatch
is more accurate.  
John

P.S.  Of the high end watches I think my buying days are over .... but,
if one were given to me I think I would like a Vacheron Constantin. 
Anybody feel charitable?

COSC's "chronometer" certification is more a marketing point than anything else.
