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. > > Hoyen > > ----------------------------------------------- > FREE!
