Very nice cal 712. Beautiful Guillochage on the case and nice contrasting oval dial against the squareness of the case. . What is the reference number? Cheers Desmond
Lol I was going to write the same exact thing. weird ! my first real job was in the Piaget Watch Bldg (650 5th Ave). http://en.m.wikipedia.org/wiki/650_Fifth_Avenue i literally worked in Marc Rich's old office. Ivan Boesky was also in the bldg. The Feds recently seized the entire building because it was owned by the government of Iran through a bunch of shell companies. Piaget was somehow involved with all the nonsense. It's a fascinating story. btw - this building was beyond nice. We had built in Piaget clocks everywhere, even the elevators. i think this is where my love of nice watches was born: http://en.m.wikipedia.org/wiki/650_Fifth_Avenue
Try adding a zero after the decimal point, as in 151.0030 or 153.0030. It also helps to use an asterisk to get a few hits on your search on the Omega Vintage Database, like so: 151.*3* - which should show you all the permutations available.
