As for the real items, the magnifying lens above the date magnifies the date 2.5 times. This means that the numbers are full of the lens. Also the magnifying lens is a bubble shape on top of the watch face. While, on fake Rolex replicas watches the magnifying lens hardly magnifies the date meaning that the number only fills up a small part of the lens. The lens is also normally very flat rather than a bubble shape like the real one.
