Hi just bought a 2254.50 off eBay and while it appears authentic the case back worries me as I found a small variation. Following the A in Seamaster up towards the top of pattern and near the case hole there appears to be an extra swirl on either side of hole at very top. Anyone see this and have opinion? Is mine fake? Mine looks like the one in the first photo except it was made in 2004 so does not have that omega laser engraving on it. The others are stock photos showing the additional wave swirl on each side very small but different then mine. And if mine was made in 2004 as seller said why does it have that pattern shown on the newer photo with the omega symbol anti counterfeit that started in 2008 I read. Ugh did I buy a fake??? Any help appreciated!! View attachment 8869
