I was reading the thread about collecting other brands other than omega and decided to have a look on ebay to see what was about. I came across this watch. I think it is a nice looking piece. The seller suggests that it might be a prototype as it has no marking on it, then again it could be something someone has thrown together. The seller is not trying to sell it as a Heuer watch, Heuer is only marked on the watch face, and no where else on the watch. He clearly states this at the bottom of his listing. The dial is a bit of a concern as it looks like it was done by hand. All things considered I think the price is a bit high for an unknown quantity. I am interested to know what you guys think. http://www.ebay.com/itm/Cronografo-Diver-Valjoux-7733-Medicale-Chronograph-Submariner-Vintage/191592483048?_trksid=p2045573.c100033.m2042&_trkparms=aid=111001&algo=REC.SEED&ao=1&asc=31478&meid=5b737f3afcfa4a00b4e4a788d75f8290&pid=100033&rk=2&rkt=4&sd=261844923026Purchases made through these links may earn this site a commission from the eBay Partner Network
