Photos of the watch alone are not enough. What you need to see is an authorized dealer stamped and dated warranty card, showing the model number as 2537.80.00 and the serial number. You can verify the serial number's authenticity through Omega. If the seller claims he "lost" it, this is a sign it may be a fake.
Also, any pictures of the Bond watch coming in standard red leather Omega boxes or any other box scream "fake". The 007 LE came in a blue leather box with gray interior trim. The 40 Years Of 007 logo can be found in blue on the inside top of the lid. Also, the white outer box should have a small blue 007 logo in the corner. It should also come with a certificate of authenticity showing the number of your watch out of 10,007 pieces produced. I wouldn't waste your money on any watch that didn't come with EVERYTHING it was supposed to come with.
I owned one of these back in 2002 when they were released, so I know exactly what a real one looks like. I sold mine on ebay, but now I wish I had kept it. The retail price was $2195 US back in 2002. All 10,007 pieces sold very quickly. To the best of my knowledge, all 10,007 pieces were given to authorized retailers (not gray market dealers), since retailers were easily getting full MSRP for them.
