An oxymoron is a contradiction in terms, such as 'deafening silence'. I saw this sign outside the ancient Roman city of Ephesus in Turkey.
'Genuine fake' is as classic an oxymoron as you can imagine. But what does it mean? The only interpretation I can derive is that the watches on sale are truly fake – there is no danger that you buy a fake Rolex and someone maliciously sells you a genuine one instead.
I suppose the real purpose of the sign is to capture one's attention. And the fact that I have taken a picture of it and put it on my blog suggests that it has succeeded. The only trouble is that I wasn't tempted to buy a watch. My Casio works perfectly well, so I see no reason to buy a Rolex, either genuine or fake.
But perhaps the sign has still been successful, as my putting it on my blog serves to encourage people to visit Ephesus (and thereby have a chance to buy one of these genuine fake watches). If so, well so be it. Ephesus is brilliant and definitely worth a visit. Here is a picture of the grand entrance of the library.
