Was looking to get this watch on eBay. http://www.ebay.ca/itm/Vintage-1964...e=STRK:MEBIDX:IT&_trksid=p2055119.m1438.l2649Purchases made through these links may earn this site a commission from the eBay Partner Network Reference belongs to a De ville. https://www.omegawatches.com/planet-omega/heritage/vintage-details/14434/ So I am wondering if the De Ville is gone due to redialing or could it be possible some of these watches came without it.
"International Collection" marked watches were sold around the world...and sometimes would be marked with a model name or blanked. A tip I picked up from... @tyrantlizardrex I think. So the answer to your question would be the latter.
Watch case shows quite a bit of wear, along with the aging to the dial, I'd say current price may already be too high. It's your money though.
