I leave it to those more familiar with these 600's (and their value) to hash-out the deal on this: http://www.ebay.com/itm/Vintage-Rar...708829817?pt=Wristwatches&hash=item4857b07e79Purchases made through these links may earn this site a commission from the eBay Partner Network
Nice, but not New Old Stock. The only more misused term on eBay than NOS is RARE. If it were solid gold it would be worth it, but a gold plated 135.011 won't sell for anywhere near that. Best I could see it selling for is $750 - and that's from a buyer who desperately wants it for some crazy reason.
Where are the other pictures - at least back, buckle and band. Especially important given the claimed condition and the appeal to please study the high resolution pictures.
Second hand is wrong. Redial, lume pip at 2 o'clock? Movement looks like it's been serviced by a gorilla on smack. $321 and that's my final offer.
This is yet another example of why 99% of vintage omegas described as NOS aren't really NOS (and some aren't even close to it).
