Serial Number 7228357 was reported as inaccurate.

Note: Please see my watch on this site for complete
details. It has been examined by a licensed Swiss
watch repair technician. Though many of the
watches produced that run would be accurate with
the information auto generated, there are "a few",
like mine that are quite different. Jewels are
wrong, production is very wrong. Only about 300 of
these 17j were made that year.
