Here's a link back to this same watch being discussed on the forum years ago by Chuck
http://www.chronocentric.com/forums/heuer/index.cgi?md=read;id=9730

Although Chuck is not convinced i look at it as possible. There are other discussions/questions about this watch on chronocentric but its always the same watch pictured. Quite a premium in price for an unproven watch.
Maybe the guys over on MWR might be able to shed some light on this one.
