Hi,

These are controversial and you'll get differing views on what a genuine one of these looks like- there are a lot of "spare parts specials" of these around.

My view is that it should have the model number engraved on the caseback and should have an engraved rotor and a plain crown- see here.

Others will tell you that the caseback is OK to be plain and no engraved rotor....but irrespective, I think most would say that the minute and hour hands on the example you've linlked to don't look right. And if there are a couple of parts that don't look right, you may well ask how can you be confident that the rest is genuine.
